Problem:

• You have a Salesforce Lightning Record Page with many related lists.
• You want to update it.
• When pressing the Save button you get the error: The ‘Dynamic Related List – Single’ component’s ‘Related List Filters’ property has an invalid value..
• You want to know which related list causes the issue.

Solution:

1. Clone the Lightning Record Page.
2. Click each related list and check the Related List Filters section for any error message in red.
3. If no error message can be found, delete each related list and click Save after each deletion.
4. When the error no longer appears, examine the last deleted related list to identify which properties caused the issue.
