Access to the path denied - Azure Function

Question

Hi. I have Azure Function that write/read data to/from CSV file located in the root folder wwwroot. I got Access to the path <csvfilename>.csv is denied error. I tried to restart the app but still the same issue. Any idea how to resolve and prevent this?

Answer 1

Hi @Adrian ,

Please navigate to the Kudu site of the Function app and check if you are able to edit the .csv file. If you are able to edit it manually, then the function app should also have access to edit programmatically. Also check the path of the wwwroot folder, it is either C:\home\site\wwwroot or D:\home\site\wwwroot, you can verify in the command window

Feel free to reach out to me if you have any queries or concerns.

Hi @Adrian

Hope I can provide some help.

I'm assuming Windows here.

Make sure you are not running from a package:

[...] When you run from a package, the wwwroot folder becomes read-only and you'll receive an error when writing files to this directory. [...]

Application setting WEBSITE_RUN_FROM_PACKAGE should not be set to 1.

Let me know if that helps.
