Visual error : a binary value was too large to be converted to text

Hi v-likosh ,

 This error could be an issue with your M script within your Power BI Desktop file. There might a data type conversion of binary before combining or opening the last file that is preventing the engine to read the record as binary. Please check it in your Power Bi Desktop. Try refreshing and checking the code.

I have also found some posts, please refer to.
