> Validate argument count during type inference
> ---------------------------------------------
>
> Key: FLINK-33255
> URL: https://issues.apache.org/jira/browse/FLINK-33255
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / Planner
> Reporter: Dawid Wysakowicz
> Assignee: Dawid Wysakowicz
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.19.0
>
>
> Currently we do not validate the argument count in
> {{TypeInferenceOperandInference}} which results in bugs like e.g.
> [FLINK-33248]. We do run the check already in {{TypeInferenceUtil}} when
> running inference for Table API so we should do the same in
> {{TypeInferenceOperandInference}} case.
> We could expose {{TypeInferenceUtil#validateArgumentCount}} and call it. If
> the check fails, we should not adapt {{operandTypes}}
