Azure Web App - Python: can't open file 'manage.py': [Errno 0] No error

Question

I am trying to deploy my Django application with Azure DevOps as a Azure Web App. The application is pipelined and build to the web app but it will not run. When I am trying to run py manage.py runserver in the Diagnostic Console i get the error below:

D:\Python34\python.exe: can't open file 'manage.py': [Errno 0] No error

Does anyone have a clue on what the issue might be? This is the first project I am trying to deploy with Azure so my knownledge is not very good. The project files are stored on the following location on the server

D:\home\site\wwwroot\<applicationName>

I am sometimes getting this error as well:

Window title cannot be longer than 1023 characters.

Filestructure

wwwroot
--- applicationname
------ api
------ applicationname
------ .env
------ db.sqlite3 (empty and not in use)
------ manage.py
------ requirements.txt

Things that have been tried to solved the issue

1. Changing the filepath in Configuration -> Path Mappings -> Physical Path after an idea from Jason Pan
2. Add a web.config file (Added in wwwroot -> applicationname -> web.config). The Config file is pasted below. This resulted in the following error: The specified CGI application encountered an error and the server terminated the process.

Web.Config file:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
 <system.webServer>

  <handlers>
    <add name="httpPlatformHandler" path="*" verb="*"
               modules="httpPlatformHandler" resourceType="Unspecified"/>
  </handlers>

  <httpPlatform processPath="D:\home\python364x64\python.exe" arguments="manage.py runserver %HTTP_PLATFORM_PORT%" requestTimeout="00:04:00" startupTimeLimit="120" startupRetryCount="3" stdoutLogEnabled="true">
    <environmentVariables>
     <environmentVariable name="PYTHONPATH" value="D:\home\site\wwwroot"/>
    </environmentVariables>
  </httpPlatform>

 </system.webServer>
</configuration>

Thank you for your help.

SOLUTION
After huge help from Jason Pan i manage to set it up as a Container Service instead and the app is now working as it should! Thank you very much Jason!

Previous we change path, we need to modify it back.

Step 1. Add Extensions.

Step 2. Add web.config.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <handlers>
      <add name="PythonHandler" path="*" verb="*" modules="httpPlatformHandler" resourceType="Unspecified"/>
    </handlers>
    <httpPlatform processPath="D:\home\python364x64\python.exe"
                  arguments="D:\home\site\wwwroot\manage.py runserver %HTTP_PLATFORM_PORT%"
                  stdoutLogEnabled="true"
                  stdoutLogFile="D:\home\LogFiles\python.log"
                  startupTimeLimit="60"
                  processesPerApplication="16">
      <environmentVariables>
        <environmentVariable name="PORT" value="%HTTP_PLATFORM_PORT%" />
      </environmentVariables>
    </httpPlatform>
  </system.webServer>
</configuration>

Step 3. Make sure that the directory structure in your wwwroot folder is the same as mine.

Step 4. Run command pip install python-decouple in python364x64.

Step 5. Then your app will be ok. If also have issues, you can troubleshoot like me.

Test Result.

In local.

After deployed.

Your directory structure should look like this. And it will work fine.

wwwroot
--- api
--- applicationname
--- .env
--- db.sqlite3 (empty and not in use)
--- manage.py
--- requirements.txt

In order to verify my guess, you can test like this in the portal.

Then restart your web app, if it works, it also can be a solution. The reason for this problem before was that the folder applicationname was added.
