"qTargetAppId": "f3e7642f-272e-467d-92a6-f9d05c23ceae",

"qSrcAppId": "a3663e9d-3704-4fdf-8050-f9e638fbbb02",

"qIds": [




"id": 2,

"jsonrpc": "2.0"




"jsonrpc": "2.0",

Hello, we are running into similar issue. Protocol tester has access to all objects. Did anyone find solution to this?

Thank you, -Stan

Bump, same issue - no more hints from the log files. Exactly the same scenario.

I've not managed to successfully call copyApp under any circumstances.

I actually want a complete duplicate of the source app, so it's annoying that I have to provide a list of objects. Is there any way to duplicate the app from the Engine API?


Re: CopyApp Method Error code 9003

Ah I have it:

What is not clear in the documentation is that the target application id i.e.:

"qTargetAppId": "f3e7642f-272e-467d-92a6-f9d05c23ceae",

is not a newly generated GUID (via GetUniqueID), but a GUID for a newly generated app.

You need to generate an empty app first.

In retrospect, I can't blame the docs because it's in there already!


Identifier (GUID) of the app entity in the Qlik Sense repository.

The app entity must have been previously created by the repository (via the REST API).

This parameter is mandatory.
