Validation fails on !Join

[heitorlessa]

Out of curiosity, have you tried with !Sub format instead of Join? And also, do you receive the same error when using the long function name "Fn::Join"?

I have a hunch what might be going on. Will take a detailed look once I get in front of the computer.

Is it failing on "sam local" calls or or on "sam validate" call?

[sanathkr]

Just pushed a PR that fixes this bug. Since this blocks all sam local commands, we will release a new version once this PR gets approved. Hang tight!

Cool, thanks for the quick turnaround!
