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:-

TypeScript

    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

TL;DR

Developers are seeking help with using Appwrite cloud functions. They are encountering a TypeError: userFunction is not a function when trying to run their code. The solution may involve ensuring the function is in the correct format and verifying the version compatibility. They are advised to refer to the documentation for proper function writing instructions.
