I finally got a chance to test this. That big error in the console you mentioned before, you should have read it because it has the “real” error in it. Your CFC has some sort of syntax error that’s causing Lucee to puke when we read the metadata.
Original Error: class lucee.transformer.bytecode.statement.ExpressionAsStatement cannot be cast to class lucee.transformer.bytecode.statement.tag.TagComponent
If you change from an injection to getInstance() in the handler, you’ll get the original error right there.
getInstance( dsl="addressValidationClient@cbAddy" )
That Lucee error seems like a bug in Lucee itself, either way it’s preventing ColdBox from mapping the module. Due to the error being real vague, you’ll probably need to take all the code out of the CFC and add it back in one method at a time until Lucee can compile it to find the issue.
