Type Mismatch
Hi vasSight
To properly diagnose the issue, it would be necessary to review the actual model. Based on the description alone, one common cause of a Type Mismatch error is when certain cells in a column don’t match the overall data type of that column.
Typical examples include:
Empty values that are actually white spaces in a Date or Number column.
Values like "NA" coming from Excel formula errors.
The best practice is to clean or fix these inconsistencies at the data source level before loading the data into Power BI. This usually prevents such errors from appearing during refresh.
If my answer was helpful please give me a Kudos and accept as a Solution.
The type mismatch error during refresh was caused by a corrupted source file. Fixing it by recreating the file resolved the issue. When refresh errors persist, consider rebuilding the source to clear hidden file problems
