Collect unusual error

Hi,

We are facing a strange error in collect last 2 days while refreshing tables from an S4 HANA system.

1. Build Package - Success

2. Test connection in Collect and Admin Datasource - Success

3. Refresh of Cranport package directly from Assemble - Success

BUT, Refresh from Collect - Fail with an error message as below.
