Error Message

Binder Error: Compressed materialization functions are for internal use only!

Stack Trace

[c-herrewijn]

not an issue, regular error is given.

The fuzzer script considers it an internal error since the error message contains the word 'internal'. This needs to be fixed on the side of the fuzzer.
