Error while reindex

[taltsafrir]

Hi, while migrating from elastic to opensearch i’m reindexing ._kibana index
and im getting this error
"mapping set to strict, dynamic introduction of [lens-ui-telemetry] within [_doc] is not allowed"
I noticed that I have this field in kibana old mapping
any ideas?

You can set the mapping parameter dynamic to true for the target .kibana index, like this:

PUT .kibana/_mapping
{
  "dynamic":"true",
  "properties":{...}
}
