1.5.4 migration error - Invalid query: Invalid cursor
I have previously successfully migrated an identical copy of this Appwrite instance to 1.5 and had no issues but now I've tried to upgrade I'm getting this error during the migration:
TypeScript
Fatal error: Uncaught Utopia\Database\Exception\Query: Invalid query: Invalid cursor: UID must contain at most 36 chars. Valid chars are a-z, A-Z, 0-9, and underscore. Can't start with a leading underscore in /usr/src/code/vendor/utopia-php/database/src/Database/Database.php:4694

TL;DR
Developers are encountering an 'Invalid cursor' error during a migration to version 1.5.4 of Appwrite due to UIDs exceeding the allowed 36 characters and containing invalid characters. The solution is to truncate UIDs to a maximum of 36 characters and ensure they only include a-z, A-Z, 0-9, and underscores.
