Mongodb search document results: no output records

i m using mongodb direction connection in dev & production enviroments.
the search operation retrieves empty collection while connection is established and no error recorded.

support: instructing to connect to cloud and via nodejs driver.

here its not the case.
any idea?

not sure why there is no response. maybe use case isnt common.

the error related to connection url of the mongodb:

DataError

toString() radix argument must be between 2 and 36
