DataFormat.Error: We Couldn't parse the input provided as a date value

How do I solve this? This error happened after I refreshed the data for the dataflow that was working properly before.

The error seems to be at a step where I am combining two queries based on a common ID in both. However, neither were nor are a Date or in that format.

Look at your data again.  In you dataflow do a test with a subset (top 1000 rows for example). Then isolate the data row with the format issue and decide how to handle that.
