<handler> Scriptprocessor could not be found in <fastcgi> application configuration

Question

Problem :

I am trying to deploy my Python Flask application in my Azure web app. I had created web app(Flask) and published the code. After publishing it, I am facing below error from the site.

The page cannot be displayed because an internal server error has occurred.

When I checked the Log, I could see the above error.

But this was the case only in my subscription(my free subscription with MSDN). But it was working fine in the Organisation subscription.

I have gone through your question and I understood it.

I had faced the similar issue in the past and so know the solution on it.

The <fastCGI> settings must be done in your applicationHost.config file (in your system.webServer section) of IIS. Just putting it into your web.config does not work (I can confirm it by testing it on a local IIS). An example of the configuration may look like as below :

<fastCgi>

  <application

    fullPath="C:\home\Python27\python.exe"

    arguments="C:\home\Python27\wfastcgi.py"

    maxInstances="16"

    idleTimeout="21600"

    instanceMaxRequests="10000000"

    signalBeforeTerminateSeconds="60"

    xdt:Transform="InsertIfMissing"

    xdt:Locator="Match(fullPath)">

    <environmentVariables>

      <environmentVariable name="PYTHONHOME" value="C:\home\Python27" />

    </environmentVariables>

  </application>

</fastCgi>

You must adjust your configuration according to above configuration.

This should help you in solving it for a local IIS where you can edit the applicationHost.config.
