Help Needed Using Appwrite Functions

Hey guys !! Can any one please help me using appwrite cloud functions. Actually migrating my whatsapp msg api from render to appwrite functions and everytime i run it getting this err:-

    at execute (/usr/local/server/src/server.js:159:28)
    at action (/usr/local/server/src/server.js:174:33)
    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)
    at async /usr/local/server/src/server.js:10:9```

for testing purpose even / which return Hello World is also giving the same err

this happens if your function isn't in the right format...did this function exist before or after 1.4?

I just added it today not sure about the version 😅

then please refer to the docs for how to write your function: https://appwrite.io/docs/products/functions/development

@Steven Okay thanks !!
