elastic search module fails to start.

I have started experimenting with this ,and i am facing something which seems to be a trivial issue ,just hard to solve for me.

"stacktrace": ["org.elasticsearch.bootstrap.StartupException: ElasticsearchException[failed to bind service]; nested: IndexFormatTooNewException[Format version is not supported (resource BufferedChecksumIndexInput(SimpleFSIndexInput(path=\"/usr/share/elasticsearch/data/nodes/0/_state/segments_2\"))): 10 (needs to be between 7 and 9)];",

Only the elastic search docker fails to start. Everything else starting up and waiting for elasticsearch to start. Does anyone has any idea what am I missing?

It was my fault i was changing elasticsearch version numbers in deployStack which caused this issue. Seems to be solved with changing to 7.9.1
