Recently we upgraded to v2032.2 (Build 12046). One of our engineers executed a schedule with multiple releases and for the builds where manual intervention was required, he was unable to retry or cancel the build using the UI. The error he got was ‘value cannot be null (Parameter ‘source’)’ :
I was able to reproduce the error myself as an admin. To cancel the deployment we had to change the task state directly in the database. Considering we use the same process to execute production releases, not being the action manual interventions will be a problem. As part of the latest upgrade we increased the per-node connections to 135 (versus default of 100). Could this be contributing to the issue?
