Hi All,
I am facing an issue while qualifying a lead when I add a member to sales team grid.

If I have add any user to this grid and try to qualify the lead, I get the following error:
"The user you're trying to add is already a member of the sales team. If you contact support, please provide the technical details."

The error log also does not mention any detail. The grid stores records from Connections(Connected from) entity.
Though, when I click on qualify button it gives the error but a new connection corresponding to the contact on lead gets created.
I do not want my users to see this message. I am not sure if I perform any wrong step.
Please help. Thanks in advance.
