Official CH changelog text
Improve joinGet error message so that it properly states that the number of join_keys is not the same as the number of right_table_keys. #87279 (Isak Ellmer).
Improved the joinGet function error message to clearly indicate when the number of join_keys does not match the number of right_table_keys.

Why it matters

This enhancement helps users quickly identify and understand the cause of errors related to mismatched join keys in the joinGet function, simplifying debugging and improving usability.

How to use it

No changes in usage are required. Users will receive a clearer error message automatically when the number of join_keys differs from the number of right_table_keys during a joinGet operation.
