Describe the bug
When the flexipage is modified and you click on Save button you recieve the following error:
"The 'SF PEG Custom List' component's 'Header Action Configuration' property has an invalid value."
I've checked all SF PEG lists on the flexipage and the Header Action Configuration has the '---' value.
To Reproduce
Steps to reproduce the behavior:
- Go to any flexipage
- Edit some fields, not necessarily a PEG list modification
- Click on Save button
- See error
Expected behavior
Click on save and save the changes
