Changes in PageBuilder Editor results in "Type Error"
Symptoms
Changes made to a PageBuilder component are immediately reverted in PageBuilder Editor
After 1 or more attempts PageBuilder Editor produces an error:
TypeError: Cannot read properties of null (reading 'removedLink')
Cause
This error occurs when a page which has been migrated from a prior environment and contains components with links configured for the prior environment which do not exist in the new environment. The import process will usually remove such links, however, if the links are not fixed the indicated error will occur.
Solution
Remove and re-create the affected component(s).
