Creating a modal after a button click shows an "Unknown Interaction" error

I've created a system which dynamically creates a sequence of embeds, components and select fields for a Setup command. My hope is that I can also add into it an option for creating a Modal, so when I need a text input from the user I can show it in a more elegant way than just "type a message in chat". Whenever I send a modal using this system (clicking a button can generate a Modal element), the modal shows up on Discord, but the bot crashes with an DiscordAPIError[10062]: Unknown interaction error. Researching, I came across this:

Showing a modal must be the first response to an interaction. You cannot defer() or deferUpdate() then show a modal later.

Does this mean that this kind of action is not possible, and that modals are exclusive to being used immediately after a Slash Command is executed, or is there a way to implement this? Error code:

/mnt/c/Users/Honie/Documents/Retool JS/node_modules/@discordjs/rest/dist/index.js:640
      throw new DiscordAPIError(data, "code" in data ? data.code : data.error, status, method, url, requestData); 
            ^

                        const modal = await this.createModal(component.modal, i);
                        return;

            }
        })

I'm not clear why you're calling i.deferUpdate() when the rest of the code before interaction.showModal() shouldn't take long to execute. You should be able to just remove that line without any issue. Calling collector.stop() also seems redundant since it has a max of 1 and would end anyways What you saw about not being able to defer modal submits is correct, however I don't think it actually has an effect on what you are trying to do in this case

HonieweenOP•17mo ago

You're right about collector.stop() and the reply being edited not being necessary, but not deferring the update causes a This interaction failed message to appear after three seconds. The collector is awaiting a response, maybe?

HonieweenOP•17mo ago

(That being said, the modal error doesn't appear anymore when not deferring the update, so that's progress.)

@Honie did you ever get this to work?

HonieweenOP•10mo ago

I believe I did make it work, but ended up scrapping the feature - returning to the same modal more than once works inconsistently I'll dig into the code later and see if I can give you a sample
