Suddenly, in our installation of bitbucket (5.5.3) with scriptrunner (5.2.10) the "scriptrunner Built-in Scripts "page doesn't load. We receive the following error by the rest endpoint /rest/scriptrunner/latest/canned/available
java.lang.NoClassDefFoundError: com/atlassian/bitbucket/internal/branch/model/configuration/BranchModelConfiguration
