Hi Brent, there is a THROW in spBlitzFirst at line 2591 that triggers validation errors in some IDE like VS Code. It is just missing the semicolon on the previous line, I see in other stored procedures there is one so I guess this is just not noticed. Sorry for the trivial (not frivolous) suggestion, but it would help some people. I don't think it is worth creating an pull request just for a single semicolon, maybe in a future release you can just press that key at the right place :)
Thanks a lot in advance.
