Hi @Badger
I'm still having the same problem, and both solutions result in a json parsing error. The same applies to flattened json data.
Error:
[2021-09-02T11:20:28,725][WARN ][logstash.filters.json ][main][a39479da327a8f2b0a3503f33c5a383682f4ba6777108aceccd46983b1e8556f] Error parsing json {:source=>"message", :raw=>" \"Added\": 44488,\r", :exception=>#<LogStash::Json::ParserError: Unexpected character (':' (code 58)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')
I even tried the same input given in this post
Also pipeline was not started
