Excel Download functionality in PowerApps via flow. The data returned in the response is invalid. Response data should be a valid json object

[Ash06]

I am trying to build an instant flow which will help me with exporting the excel download of the gallery items and store in my One drive. Since I am pretty new around, tried to do a bit of googling and implemented this. However, now i am getting errors in Power Apps. Kindly help me please.

Onselect of the Button below is the syntax defined:

ForAll(Gallery6.AllItems,Collect(colDataExported,{Business: ThisRecord.Business,'Application / Asset Name': ThisRecord.'Application / Asset Name'}));
Test_Excel.Run(JSON(colDataExported,JSONFormat.IncludeBinaryData & JSONFormat.IgnoreUnsupportedTypes));Clear(colDataExported)
