Hey @praja96 !
I’m not sure exactly how to un-truncate an error message. My bet is there is something in that visual specifically that is wrong or missing that would be hard to define compared to other visuals. Because the part of the error message we can see is pointing to the visual title, I would suggest double checking that you don’t have a parameter that doesn’t exist being used in a subtitle or something like that.
You could try using the following CLI command as well and exporting this out to json:
