[Bucardo-general] AWS RDS Aurora - Bucardo delta replication Issue

[Mahendra Kale]

Hi Team,

For delta replication between source(AWS Aurora PostgresSQL v9.6) and destination (AWS Aurora PostgresSQL 10.17) we are using bucardo v5.6.0.
We have setup bucardo on an EC2 instance and have configured source and destination endpoints. however we are getting below error when we start the sync process

Last error:              : Failed : DBD::Pg::st execute failed: ERROR:  query string argument of EXECUTE is null CONTEXT:  PL/pgSQL function bucardo.bucardo_delta_check(text,text) line 24 at EXECUTE at /usr/local/share/perl5/Bucardo.pm line 3407. Line: 5037 Main DB state: ? Error: none DB sourcedbtest state: 22004 Error: 7 DB targetdbtest state: ? Error: none  (KID 213434).

Please let us know anything else need from our side.

Note:- This is a production issue and we have a tight deadline so could you please look into this issue and help us to resolve it asap.

Thanks & Regards.
Mahendra A. Kale
