The query-correctness-tests (1, 2, 3, 4) encountered an issue with a malformed query that was uncovered during the implementation of SERVER-99569.

Below are some examples of the issues found, it's best to look at the evergreen logs for each individual failure.

Issue 1:

query-correctness-tests-1/generated_tests/lemur-1771702139027/good1-8.1

The problem occurs because a variable in the $fill stage is both defined and referenced within the $let clause, which violates the rule that any variable used inside a $let must be defined outside of it.

Issue 2:

query-correctness-tests-1/generated_tests/shag-1771702139034/good1-8.1

Expression $eq takes exactly 2 arguments. 1 were passed in.
