Did not find expected '-' indicator in app.yml

[adrianbblk]

Hi Everyone,

I just try to rebuild the app and I get this error:

(<unknown>): did not find expected '-' indicator while parsing a block collection at line 11 column 3 -e LANG=en_US.UTF-8
YAML syntax error. Please check your containers/*.yml config files.

Line 11 in my app.yml

- "templates/cron.template.yml"

I need some help to fix it. Thank You

Perhaps you have a tab rather than a space?

There are yaml checkers on the net. You will need to be able to copy and paste rather than take a picture.

What changes did you make?

Looks to me like the ratelimited and socketed lines have one too many spaces in front. They should have the same number of spaces as the 5 templates above, not the 2 commented out templates.

Hi again,

Even I moved the line 11:
- "templates/cron.template.yml"

I get the error on the same line, 11 col 3 where now is

- "templates/postgres.template.yml" This line was there.

Thank You! That fix the issue. I was still looking at the line 11.

You have an extra space or two In front of the - on the ratelimited and socketed lines it doesnt line up with the above section. Also as mentioned above ensure that only spaces not tabs are used.
