Process failed to take call off hold

[JJack]

Hi,

I've had a failed process for a call at a node to take the call off hold (set status to open).
This node followed a decision checking an external authorisation outcome.
Saving and restarting the failed process, without any changes, let the process take the call off hold, record the approval decision, and continue okay.

The error appears to have been 'Failed to commit database transactions':

0.128056s    INFO    Unsuspending process at node 'Take off Hold' (id=flowcode-...)

Can you provide any advice?

Thanks, Jill.
