Bad key in untransform: __v

Hello
Parse-server dashboard is showing this error
bad key in untransform: __v
When data comes from mongoDB using streams.
Note- parse-server is already setup.

what type of data is that?

the parse server dashboard doesnโ€™t support Decimal type in case that decimal types were added

this is mongoDB __v:0 version data

I donโ€™t know what is that

how i can enable this parameter on parse server dashboard
because all mongodb support this parameter by default.
