Error 'couldn't find the record you are trying to access' when using Global Actions in Lightning

Root Cause

This error is typically caused by the global action being assigned the default placeholder --Master-- record type. Salesforce requires a specific record type to be selected for global actions to function correctly.

Resolution Steps

To resolve this an administrator can select an available record type for each affected global action:

1. From Setup, enter Actions in the Quick Find box, then select Global Actions.
2.  Click the Edit action link for the affected Actions
3. Change the Record Type field's selection from --Master-- to another available record type.
4. Save.

Note

• This error also occurs when creating a 'New Task' after converting a Lead. Ensure that the Record Type selected in the 'New Task' global action is assigned to all Users either via the Profile/Permission Sets on the Task object.
• This issue will occur in the Related Record lightning component if they use the default Create New action, and that they will need to use a different action with a specified record type.
