According to the AMP HTML specs, I believe you need to remove all new lines from the AMP boilerplate code because it's validated with regex (regular expressions) so all new lines are being read as "\n" causing errors.

Direct from the docs

AMP Boilerplate Code ('head > style[amp-boilerplate]' and 'noscript > style[amp-boilerplate]')

AMP HTML documents must contain the following boilerplate in their head tag. Validation is currently done with regular expressions, so it's important to keep mutations as minimal as possible. Currently, allowed mutations are: (1) inserting arbitrary whitespace immediately after the style tag opens, and immediately before it closes; (2) replacing any space in the snippet below with arbitrary whitespace.
