Did not find expected key while parsing a block mapping at line 40 column 3 -e LANG=en\_US.UTF-8  
YAML syntax error. Please check your …

app.yml line 39

env:  
LANG: en\_US.UTF-8  
# DISCOURSE\_DEFAULT\_LOCALE: en

So I messed up my smtp by putting smpt. I ran ./discourse-setup a second time and fixed it. it made a app.yml.bak. the new app.yml is fixed but when I run ./discourse-doctor It still has the typo for the smtp url.  
I’m not sure how to fix the syntax error so the container will rebuild.  
Thanks for your help.

Fixed Do to the trouble shooting I added ’ ’ around my email address. this put double ’ ’ email ’ ’ remove extra quotes and it works.
