Error getting value from 'TagsString' on 'Qsda.Shared.Model.Extended.MasterMeasureMeta'

Hello

My application contains tags in the master measures. When analyzing the application, QSDA Pro cannot retrieve these tags, resulting in an error. Even after deleting the tags, the error still appears.

What version of QSDA Pro?

hi.
have the same problem.
QSDA PRO version 3.7.1

Application was imported from Qlik Cloud to local Qlik Sense hub version May 2026 (15.13.8)

Cleaning the tags by hand would clearly be impractical in terms of time

What can be done? Thank you.

I’m unable to recreate the condition where you get this error. However, I will add some defensive code that I hope will resolve this issue for you. The change will be included in service release 3.7.2, scheduled for the week of Aug 10
