@ainthapanya-sqc Where's the original chart you used for Fluent Bit to reproduce this? There's lots that float around,

Also, that mapping parser exceptions should be coming from Opensearch API downstream to Fluent when it attempts to bulk push the docs.

Are you sure your mapping on the index aren't misconfigured? As the implication is that an index mapping is wrong on your index (Object, not String/Keyword for example.)
