Share your js console

js console log
localStorage cleared
desk.min.js:11055 Cleared App Cache.
desk.min.js:11089 localStorage cleared
desk#Report/Material master/new:1 Uncaught SyntaxError: Unexpected token u in JSON at position 0

There seems to be an issue with your JSON (report document)

Can someone help me with this ?

@ragav How are you creating the report? I think you are directly creating the Report record. In that case, that is not the correct way, you need to go Report view of the particular document and then select the required columns and filters and save the report. Report record will be automatically created.

I did exactly as you said but it is not working sir

Hi all
I’m having exactly the same issue. When I try to build a Builder Report for Item , and then from Item I go to report on the left Side menu, the Report page is showed empty and the Webapp stop to work , it became unresponvie and I have to cloe it. From Console i see this Exception:

“Uncaught SyntaxError: Unexpected token u in JSON at position 0”

I used Developer → Report to build the report
thanks for your attention really appreciated
