There is a Text Label that shows lookup value from SharePoint list. This Label text is set ThisItem.'Department_x002f_Division'.Value and work normally. However, it suddenly stops working. The Text Label shows error as bellow:
name isn't valid. this identifier is not recognized.
If I change ThisItem.'Department_x002f_Division'.Value to ThisItem.'Department_x002f_Division'.Id, it will works and show Id Of Lookup field.
I have already check that I do not lookup to LinkToItem value, and no additional value from Lookup column. Also, I remove gallery and start from scratch without success.
Please let me know this kind of issue.
Thanks for reading!
