According to the error message: ``` and else (None) to common types in CASE WHEN expression ``` https://github.com/apache/datafusion/blob/d460abb63f6ff3abce6de022834f6f17c77db411/datafusion/optimizer/src/analyzer/type_coercion.rs#L891-L899 It seems that DataFusion fails to get the type of the `else` expression. I'm not familiar with `delta-rs` merging. Do you know what kind of expression would be generated by `delta-rs`? -- This is an automated message from the Apache Git Service.
