Or  if spacing is not the problem  it might want the parent directory name rather than the file name   Not   dev appserver helloapp pyBut   dev appserver hello   For example   Johns-Mac hello john  dev appserver py helloworld py Traceback  most recent call last     File   usr local bin dev appserver py   line 82  in  lt module gt       run file   file    globals          File   Applications GoogleAppEngineLauncher app Contents Resources GoogleAppEngine-default bundle Contents Resources google appengine google appengine api yaml listener py   line 212  in  GenerateEventParameters     raise yaml errors EventListenerYAMLError e  google appengine api yaml errors EventListenerYAMLError  mapping values are not allowed here   in  helloworld py   line 3  column 39   Versus  Johns-Mac hello john  cd    Johns-Mac fbm john  dev appserver py hello  INFO     2014-09-15 11 44 27 828 api server py 171  Starting API server at  http   localhost 61049 INFO     2014-09-15 11 44 27 831 dispatcher py 183  Starting module  default  running at  http   localhost 8080

I ve seen this error in a similar situation to mentioned in Joe s answer   description  Too high 5xx responses rate      Value     gt  0 05   We have a colon in description value  So  the problem is in missing quotes around description value  It can be resolved by adding quotes   description   Too high 5xx responses rate      Value     gt  0 05

My issue was a missing set of quotes   Foo  bar  baz    should be  Foo   bar  baz

Maybe this will help someone else  but I ve seen this error when the RHS of the mapping contains a colon without enclosing quotes  such as   someKey      another key  Change to make today  work out more  should be  someKey      another key   Change to make today  work out more

Another cause is wrong indentation which means trying to create the wrong objects  I ve just fixed one in a Kubernetes Ingress definition   Wrong  - path         backend         serviceName   lt service name gt         servicePort   lt port gt     Correct  - path      backend      serviceName   lt service name gt      servicePort   lt port gt

Change application climate-change  to application  climate-change  The space after the colon is mandatory in yaml if you want a key-value pair   See http   www yaml org spec 1 2 spec html id2759963
