This seems like a massive in-line code size, but not out of the question.

Looks like there used to be a character restriction on inline code based on some old stackoverflow answers, but that may have been removed.

I would like to see if an inline lambda will deploy with more than 4kb. The template being synthesized is not a good indicator of whether it works or not since it would be a CFN limit that we do not validate currently.

I changed it to be the resulting zip file cannot exceed 4MB. I think that's the only limit we can deduce from the docs?

Hey @msambol, I am doing some work with lambda assets, so I will give this a spin. I still think this may be an error in their documentation. The limit for a CFN template as a whole uploaded to s3 is 1 MB (CFN limits).

I'd love to be wrong here, but I am feeling lucky with this prediction! I'll get back to you shortly.
