If you or someone in your organization received an error message when trying to update a Task or a Board that says:
Error: Type: Required fields are missing: [type]
In Summer ‘19, we introduced a new feature: List Type. The new functionality within Lists on the Board includes a new required field: Type.
During the upgrade, the Lists in existing Boards that were created prior to July 2019 will have a List Type value pre-populated. However, some organizations may experience an issue the List Type values do not get fully pre-populated during the upgrade.
A Taskfeed Admin User or a Salesforce Administrator can push a button in the Taskfeed Application Settings page that will quickly fix the issue.
Just follow these steps:
1. From the Taskfeed tab, open the wrench icon located on the lower left-hand corner.
2. Select Application Settings
3. Go to the Background Processes tab
4. In the Migrate List Template Type section, click Run Now
