I have a grammar and when I try to generate using the MWE workflow, I get an error which looks like its to do with the generated PSI grammar file:

attribute is not a token, parameter, or return value: Keyword_9_1ElementType

Full MWE output with error here:

As a workaround you may move dollar sign to a terminal rule
