I tried importing dashboards using SWQL Studio and it keep giving this error even after I used Notepad++ to linearize the json file.
I think there is a limit, I did it using the .fucntion load tutorial and Powershell 7.5.
I think even though you receive this error, if it returns as ' nil = "true" ', you can use the modern dashboard. Please search your dashboard under the Settings> Manage Dashboard > Modern
Hi this is normal to see.
