Breaking events JSON

For some reason the LINE_BREAKER option for Splunk keeps turning a JSON log file into a single event, ignoring everything after the first event. Does anyone have any experience with breaking the events up for the following log?:

{"aModLR":{"attributes":{"affected":"topology/pod/node/av/node","cause":"transition","changeSet":"targetMn (Old: AAA, New: BBB)","childAction":"","clientTag":"","code":"E69","created":"2019-07-18T16:38:41.501+02:00","descr":"Node modified","dn":"subj-[topology/pod/node/av/node]/mod-43243","id":"23432","ind":"modification","modTs":"never","sessionId":"ABCD",severity":"info","status":"","trig":"config","txId":"18374686479671625257","user":"admin"}}},{"aModLR":{"attributes":{"affected":"pluginPolContr/pluginPol","cause":"transition","changeSet":"verifySignature:enable","childAction":"","clientTag":"","code":"E68","created":"2019-07-18T10:31:11.748+02:00","descr":"PluginPol created","dn":"subj-[pluginPolContr/pluginPol]/mod-1234","id":"12345","ind":"creation","modTs":"never","sessionId":"ABCDEF123",severity":"info","status":"","trig":"config","txId":"5645","user":"admin2"}}}

I've tried BREAK_ONLY_BEFORE = {"aModLR" or LINE_BREAKER = {"aModLR() but it still turns it into a single event.

LINE_BREAKER = \{\"aModLR\"

I think you need to escape the string.

I tried extracting fields with a query as an example.
