Does anyone knows what could cause this issue by rebuilding app?

YAML syntax error. Please check your containers/*.yml config files.
Something is wrong with your yml file. Note that yml is incredibly sensitive to whitespace. Try copying your file here: http://www.yamllint.com/. If you still can’t determine the issue, please upload your entire app.yml here for us to take a look. Make sure to remove sensitive information like passwords first!
Tabs have been outlawed since they are treated differently by different editors and tools. And since indentation is so critical to proper interpretation of YAML, this issue is just too tricky to even attempt.
I don’t know what text editor you are using to edit the file, but I suspect you are using tab to create what visually looks like the correct number of spaces to you, but is not the correct number of spaces.
That is, when you edit, use the space bar and not tab.
I’m using the nano editor thru the terminal to make some changes. However for attaching file here I’ve connected to my Droplet by using Cyberduck and copied the body of the YAML file by using a usual text editor on Mac
Does nano editor and text editor convert the tab gaps to the space gaps? I’ve just saved that file on the text editor and upload to the containers folder, but didn’t help
Also, I’m wondering, why the YAML checker didn’t show tab spaces for you, when you checked the app.yml file, if there it could happen?
Cleared my app.yml by connecting thru Cyberduck (made it blank)
Copied and editied the information below
The already checked information on http://www.yamllint.com/ copied to my app.yml file with blank field
Saved and rebuild the build with plugins
Profit
Thanks for everyone
