found unexpected end of stream #38

Closed skanagal closed 4 years ago

skanagal commented 4 years ago

I get an error that says "found unexpected end of stream" when it reads through the YAML. It could be a problem with my setup but it worked before with the same YAML file but different cEOS image.

Any ideas? Did anything change? Thanks!

It was a simple typo in my YAML file. Apologies for the spam.
