No matter what I try I keep getting syntax errors (mapping not allowed, or can not fine expected ":") on line 67 external: true ( (volumes section at the end). Can someone help me out with the format please? I have tried using quotes, tried messing with indentions and spacing etc, and no matter what I get an error. Thanks!!

CodePudding user response：

I think you are just missing the ":" after volumes.

Here is the updated compose file.
