bug when connecting a blob storage

[fer21]

I am connecting a source through an Azure blob storage to power bi, when I transform the data and save the changes I get this error. What could it be?

Hi  @fer21 ,

Are you using the latest version of Power BI Desktop? Please provide your version information and some detailed of the error (be careful not to include sensitive information) to describe the problem.
I tried to do a simple test but it doesn't seem to reproduce the problem, any more information would be great.

Best regards.

Hi  v-xiaoyan-msft

Yes, of course it turns out that I am obtaining information in the blob storage of a platform called playfab, when making the connection as seen in image 1 I load the data but starting with the fact that it is in parquet format, in addition to that I proceed to combine the column that It has the binary files, where a single file is already made with all the data, but seeing that since I combine the binaries it already generates the problem. as in image 2,  Also seeing the steps I get that in image 3 from that moment it generates the error when I combine the binaryimage 1 before combining the binariesImage 2 where the binaries have already been combined and generate more information but the error appears.Image 3 error steps
