Qlik Compose - 2021.08 - Object Reference not set to an instance of an object error

We get the following generic error while regenerating the tasks in Qlik Compose 2021.08 version:

Object reference not set to an instance of an object.




  • Qlik Compose 2021.08



The error can be for many reasons but in the case it was because of concatenate function on one of the mapping columns. Something like 'ABC|DEF|ACCOUNT|' || TO_VARCHAR(${ID}). This issue happens after we upgrade Compose from 2021.05 to 2021.08.

The resolution is to rebuild the function again manually. There is no apparent reason why it might happen and is intermittent.

We have the same error. I rebuild the function again and I still got this error.
Does we also need to rebuild the filters? Or is there something else I can check?

Kind Regards,

I would recommend you post about the issue directly in either the Qlik Compose for Data Lakes or Qlik Compose for Data Warehouse forums to make use of our engineers and community members active on those places.
