JSON integer is too large or small error

Hi All - 
I am looking for help with a Power Query error on an existing report that has refreshed in PowerBI desktop perfectly fine until this morning. The resulting error is as follows.

"JSON integer 4294967295 is too large or small for an Int32. Path '[25].MaxLength', line 1, position 9475."

 

Where do I look for the error based on the line and position given and is this in the Power Query Advanced Editor?
Is it soley limited to the 1 queries the error is referencing or could it be in one of the others and connected with lookup columns?
Should I be looking at changes within the data source?


I appreciate any help provided.

Hello,

You must convert the data to int64, this can be done through power query in the following button

I followed the same process in power query but still it is throwing the same error.

Did you select all columns before ? did you make it for all tables ? 
hope this helps and fix 

I confirm that the following has worked for me: Enter Power Qwery editing mode, select ALL the columns and click (to add the process step) the Transform>Detect Data type button. Many thanks to all

it works for me, thank you so much
