ERROR: there should be a single space or newline before a closing brace on line 11 (check: manifest_whitespace_closing_brace_before)
WARNING: missing trailing comma after last element on line 11 (check: trailing_comma)

It looks to me that the issue you are experiencing is being caused by a conflict of interest with two community plugins.

1. puppet-lint-manifest_whitespace-check detects and fixes an issue on line 11/12 of your example
2. puppet-lint-trailing_comma-check then tries to fix an issue at the index of the token on line 11.
3. When trailing_comma_check tries to apply the fix (tokens.insert(idx, comma)) it fails because idx is nil and not a valid index.
4. I think it's nil at this point because the position that the problem was originally registered at no longer exists (due to step 1).
