Suggested Fixes​

  • Ensure that the $dynamicAnchor value does not contain any forbidden characters.
  • Ensure that the $dynamicAnchor value follows the regex pattern: ^[A-Za-z_]+[A-Za-z0-9-_.]*$
  • Use only alpha-numeric characters, underscores, hyphens, and periods.
  • Ensure that the starting character is a letter or underscore. Numbers and other symbols cannot be used to start an $dynamicAnchor value.
