Solution: adjusting the database schema to allow longer strings. Running catalogs would need to migrate / update their database. The strings in the example have about 700 characters. The update contains a new limit for the diduri, the subjectid and the issuer of 2048 characters, which is around the max URL length different browsers and services support.
