glyph_report.pl fails before building the table at the end

[Gartral]

glyph_report.pl is failing with an odd error when it should produce the table of available recipes, the exact error follows

YAML Error: Expected separator '---'
Code: YAML_PARSE_ERR_NO_SEPARATOR

I've looked in both my login.yml and the yml file that's embedded into the scripts and I can see there's a separator in both. I'm stumped and posting here was a last-resort. Thank you kindly for your understanding.
