Import Qlik Sense App fails with: The REST API call timed out between services.

[Anonymous]

Attempt to import an App and the user sees the following error message:

The REST API call timed out between services.

The *_system_engine logs show the following error:

Server: ImportApp_impl caught extended exception 415: Unsupported Media Type
 

Environment:

• Qlik Sense Enterprise on Windows, September 2019 or higher
  
  

Cause:

Migration anomaly
 

Resolution:

A first possible workaround to attempt, which solves the issue in some cases:

1. Install Qlik Sense Desktop on a personal desktop/Laptop. See How to download Qlik Sense Desktop.
2. Put the App in the directory with other apps accessed by Qlik Sense Desktop. 
3. open the app in data load editor (DLE). 
4. make any minor change that forces you to save the app.
5. save the app
6. import the App into the Central Node QMC 

The same steps (import the app, modify it slightly and re-export it again) can also be attempted on a SaaS tenant.

Should the issue still persists, repeat the steps above by gradually removing elements from the app in the Desktop Client, until the one causing the issue is found.
Should this still not solve the issue, proceed with further troubleshooting.

I'm 18 months late, but maybe this will help someone else.

This would happen consistently for an app of mine when trying to import from Qlik Sense Desktop to Qlik Sense Enterprise on Windows Server.

I was able to import my app only after removing all of the data connections from the app on Qlik Sense Desktop, making a small change to the data load editor script (such as adding a comment) and then saving the app.

The key seems to be to removing the data connections before trying to import.
