msrest import error while deploying to azure app

[gdsuser1992]

We are creating a flask app. It is working fine in local environment (no version conflict issues). Recently, when we tried pushing the code to azure app service, after successful build, when we access the webpage, its giving a 502 error.

We tried to identify the issue and when we checked the logstream, the following error was found :

Are we facing any version conflict issues with azure-core and the msrest ?

We are not adding the msrest package in requirements.txt and its loaded by default when we publish it to the app service.

We tried to change the version of azure-core to 1) the latest version 2) 1.9.0 3) 1.11.0 - All these still end up giving the same error.

Is there any work around for this issue ?? Please help.

Closing the issue. Tried with azure-core version 1.24.0 and it fixed the problem.
