I'm attempting to Merge Join two data sources. I ensured the metadata matched and that the sort key was present in the metadata, but it is still giving me the error:
Both inputs of the transformation must contain at least one sorted column, and those columns must have matching metadata."
All of the support articles and matching forum questions all mention metadata and sorting. I even type cast the right data set to match the left… Not sure what to do here. Flow and metadata are pictured. First is the left join, second is the right join. The last entry is the column I wish to join on in both metadata tables.

There is a setting where you can tell the Merge Join that the incoming information is sorted, although in the documentation, the Sort task is supposed to properly set these properties. I wonder if it's because you have other tasks after the sort, and the IsSorted property is getting set back to False.
The documentation tells you how to set those settings manually.
