Hello,

Could you please indicate on which talend build version you got this issue?

Did you follow up online user guide about:TalendHelpCenter:Centralizing MongoDB metadata to retrieve schema correctly?

Best regards

Sabrina

Hello,

Did you create a Mongo connection and export as context? Are you checking out ' replica set address' option when set up your Mongo DB connection?

Best regards
