The key didn't match any rows in the table

I am using a sharepoint Folder connector and it was workig finem bit then I am getting below error, I know the cause for this error is someone may have changed the column name in the source file. 


I wanto to get to the actual file which has error, I have tried using the TRY function in Power query to trap the error and then expanded to the Has Error column which has TRUE in it, but then I cannot find any value with TRUE meaning there isn't any error.


I even tried the KEEP ERROR PQ technique it then just throw me below message shown in the pic


Is there a way in Power query on how to get to the problematic file (considering my sharepoint location has more than 100 files inside it) Therefore, to open individual files and cross check for missing or reanmed column name is difficult task
