I have created an multichannel outbound campaign and ran it after adding segment, strategy, action to it.
It is completed successfully but has not generated any results out. i.e. it couldn't send out ay emails as per the expectation.

Below is the only line in the logs:

2021-02-01 14:16:53,785 [ns], Partitions=[92]] [  STANDARD] [                    ] [                    ] (        mkt.offer.OfferBuilder) ERROR   - validateProposition - Detected invalid strategy result with key: [/Service/Account/Current]

attached the screenshots of campaign where the final result is not shown anything and the dataflow of the campaign where the persistresult component from df_processoffer has not filtered any results.
