How do I fix "Error 400 on SERVER: (<unknown>): did not find expected key while parsing a block mapping at"?
When using Puppet with a Hiera data source I get this error:
Error 400 on SERVER: (<unknown>): did not find expected key while parsing a block mapping at line 19 column 3
As the file is <unknown>
I have no clue where my error is - it only indicates a line number and column. The only thing I know is that I altered a lot of data in my Hiera yaml data.
How do I fix this?
