Building Wasp app that uses Replicate API, Error submitting images to the API, 404

Hello, I'm building on top of the Wasp SAAS template and I want to make use of models on Replicate.com to run in my app. The issue is that I think I made everything as in /docs, added the replicate and multer dependencies in main.wasp, made a simple front-end to upload two images and a prompt, but when I try to submit and pass it to the actual API I get errors: http://localhost:3000/api/operations/ProcessImage 404 (Not Found) ImageUploader.tsx:54 Error submitting images: AxiosError  message: 'Request failed with status code 404', name: 'AxiosError', code: 'ERR_BAD_REQUEST' Any tips on how to solve this and actually make my Wasp app to communicate with Replicate's API? extra context: this is the action in my main.wasp: action ProcessImage { fn: import { processImage } from "@server/processImage.js", entities: [User] } any my ImageUploader.tsx where /api/operations/ProcessImage seems to be 404 (Not Found)? const handleSubmit = async () => { if (faceImage && poseImage) { //model parameters here try { // URL is derived from the action name const response = await axios.post('/api/operations/ProcessImage', formData, { headers: { 'Content-Type': 'multipart/form-data', }, }); console.log('Model output:', response.data); // Response here } catch (error) { console.error('Error submitting images:', error); } } };
