Custom Job ReferenceError: process is not defined at config.ts:41:20

job processCsvData {
  executor: PgBoss,
  perform: {
    fn: import { processCsvData } from "@src/client/operations"
  },
  entities: [User]
}

job processCsvData {
  executor: PgBoss,
  perform: {
    fn: import { processCsvData } from "@src/client/operations"
  },
  entities: [User]
}

Declaring and importing my function in main.wasp works fine, importing it in the frontend like so import { processCsvData } from "wasp/server/jobs"; seems to work fine as well, but when I try to invoke it in anothed function I have the whole frontend crashes throwing the said error but nothing in my terminal?

try {
      const res = await processCsvData.submit({
        csvData,
        emailColumnIndex,
      });
    } catch (error) {
      console.error("Error invoking Lambda:", error);
    }

try {
      const res = await processCsvData.submit({
        csvData,
        emailColumnIndex,
      });
    } catch (error) {
      console.error("Error invoking Lambda:", error);
    }

Any help would be appretiated

Hi @fustuk.. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the information provided in the knowledge sources, it appears that you're encountering an issue related to server-side code being executed on the client-side. This is a common problem when migrating to newer versions of Wasp or when there's a mix-up between server and client code. Let's address this issue step by step: 1. The error "ReferenceError: process is not defined" typically occurs when server-side code is being executed in the browser environment Github Issue #620 (https://github.com/wasp-lang/wasp/issues/620). 2. Your job declaration in main.wasp looks correct. However, the issue arises from how you're importing and using the job on the client-side. 3. The line import { processCsvData } from "wasp/server/jobs"; is problematic. Jobs are server-side constructs and should not be imported directly on the client-side Docs: Using Jobs (https://wasp-lang.dev/docs/advanced/jobs#job-definition-and-usage). 4. To fix this, you need to create a separate client-side operation (action) that will trigger the job on the server. Here's how you can do it: a. First, create an action in your main.wasp file:

   action triggerProcessCsvData {
     fn: import { triggerProcessCsvData } from "@src/actions/triggerProcessCsvData.js",
     entities: [User]
   }

   action triggerProcessCsvData {
     fn: import { triggerProcessCsvData } from "@src/actions/triggerProcessCsvData.js",
     entities: [User]
   }

b. Then, implement the action in src/actions/triggerProcessCsvData.js:

   import { processCsvData } from 'wasp/server/jobs'

   export const triggerProcessCsvData = async (args, context) => {
     const { csvData, emailColumnIndex } = args
     return processCsvData.submit({ csvData, emailColumnIndex })
   }

   import { processCsvData } from 'wasp/server/jobs'

   export const triggerProcessCsvData = async (args, context) => {
     const { csvData, emailColumnIndex } = args
     return processCsvData.submit({ csvData, emailColumnIndex })
   }

c. Finally, on the client-side, import and use the action instead of the job directly:

   import { triggerProcessCsvData } from 'wasp/client/operations'
// In your component or function
   try {
     const res = await triggerProcessCsvData({
       csvData,
       emailColumnIndex,
     });
   } catch (error) {
     console.error("Error processing CSV data:", error);
   }

   import { triggerProcessCsvData } from 'wasp/client/operations'
// In your component or function
   try {
     const res = await triggerProcessCsvData({
       csvData,
       emailColumnIndex,
     });
   } catch (error) {
     console.error("Error processing CSV data:", error);
   }

5. Make sure you're using the latest version of Wasp, as there have been improvements in handling jobs and server/client code separation Discord: Error building after migrating Wasp to 0.12 (https://discord.com/channels/686873244791210014/1212533517360177253). 6. If you're still encountering issues, try running wasp clean and then wasp start to ensure all dependencies are correctly rebuilt Discord: nothing shows up in localhost:3000 after wasp start (https://discord.com/channels/686873244791210014/1213958217537814640). By following these steps, you should be able to resolve the "process is not defined" error and properly trigger your job from the client-side. Remember, jobs are meant to run on the server, so we need to use actions as a bridge between client and server when triggering jobs. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @fustuk., I seem to be having a bit of trouble. Don't worry though, I've pinged my support and they will try to fix me up! :technologist: Perhaps try again in 15mins?

Great, issue resolved @kapa.ai how can I access the current user id from my job?

kapa.ai•4mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- To access the current user ID from a job in Wasp, you need to pass it as an argument when submitting the job. Jobs in Wasp don't have direct access to the user context like actions and queries do. Here's how you can achieve this: 1. First, modify your job definition in main.wasp to accept a user ID parameter:

job processCsvData {
  executor: PgBoss,
  perform: {
    fn: import { processCsvData } from "@src/server/jobs/processCsvData.js"
  },
  entities: [User]
}

job processCsvData {
  executor: PgBoss,
  perform: {
    fn: import { processCsvData } from "@src/server/jobs/processCsvData.js"
  },
  entities: [User]
}

2. Then, in your action that triggers the job, pass the user ID:

import { processCsvData } from 'wasp/server/jobs'

export const triggerProcessCsvData = async (args, context) => {
  if (!context.user) {
    throw new HttpError(401, 'User not authenticated.')
  }
  
  const { csvData, emailColumnIndex } = args
  return processCsvData.submit({ 
    csvData, 
    emailColumnIndex, 
    userId: context.user.id 
  })
}

import { processCsvData } from 'wasp/server/jobs'

export const triggerProcessCsvData = async (args, context) => {
  if (!context.user) {
    throw new HttpError(401, 'User not authenticated.')
  }
  
  const { csvData, emailColumnIndex } = args
  return processCsvData.submit({ 
    csvData, 
    emailColumnIndex, 
    userId: context.user.id 
  })
}

3. Finally, in your job implementation (src/server/jobs/processCsvData.js), you can access the user ID:

export const processCsvData = async (args) => {
  const { csvData, emailColumnIndex, userId } = args
  
  // Now you have access to the userId and can use it in your job logic
  console.log('Processing CSV data for user:', userId)
  
  // Your job logic here...
}

export const processCsvData = async (args) => {
  const { csvData, emailColumnIndex, userId } = args
  
  // Now you have access to the userId and can use it in your job logic
  console.log('Processing CSV data for user:', userId)
  
  // Your job logic here...
}

This approach ensures that you have access to the user ID within your job. The user ID is passed from the client, through the action, and then to the job. Remember that jobs are executed asynchronously, so the user might not be logged in anymore when the job actually runs. If you need to ensure the user still exists or has certain permissions when the job runs, you should check that within the job itself using the passed userId. Docs: Auth Overview (https://wasp-lang.dev/docs/auth/overview#using-the-contextuser-object) shows how to access the user in actions, which we've adapted for use with jobs. Docs: Data Model Operations Overview (https://wasp-lang.dev/docs/data-model/operations/overview) provides more context on how operations like actions work with authentication in Wasp. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @fustuk., I seem to be having a bit of trouble.

Ok yeah you can't use Jobs on the frontend, they are server thing! @fustuk. all good, kappa helped?
