Write files to azure function

Question

I have an azure function that take some files from storage account and write them inside the function , whene I run locally it works but whene I deply it shows this error

Result: Failure Exception: OSError: [Errno 30] Read-only file system

this coming from a code like this inside the function

 with open("./path/Data.csv", "wb") as my_blob:
        blob_data = data.download_blob()
        blob_data.readinto(my_blob)

Answer 1

This is might be because of the path as it is read-only. Try using /tmp folder instead. In your case you can use open("/tmp/Data.csv", "wb").
