[DataFormat.Error] We found an invalid value in JSON input. Only 'true', 'false', or 'null' are supp

When I increase the date range for my DAX query from Date.InPreviousquarter to Date.InPreviousyear, I keep getting the following error, I am parsing multiple JSONs one after the other but am not able to understand the issue, is there a date range to the JSON data that can be parsed by PowerBI DAX engine

 

[DataFormat.Error] We found an invalid value in JSON input. Only 'true', 'false', or 'null' are supported.

 

Source of my data is Azure table storage and basically I am transforming/ aggregating data in PowerBI Desktop before viewing it on PowerBI UI

 

Any help will be appreciated, this is a critical insight to our business to baseline the KPIs that we want to track
