Hello @Erkany6312
The error message needs to be updated in the localization XML. The GetLocalizedStringsTransformationClaimType value is used to copy localized strings into claims.
If ElementType is set to ErrorMessage, this element specifies the identifier of an error message. See Localization string IDs for a complete list of the UxElement identifiers.
Kindly refer to Sign-up or sign-in error messages for default value and refer to Sign-up or sign-in example for localization XML to be edited with the text you want for end user.
Please do let me know if you have any further queries in the comments section. If this does not suit your scenario then please share the technical profile and user journey orchestration step you want to edit the message in.
Thanks,
Akshay Kaushik
