In 2.5.0p1 the configuration of the GRPC- and HTTP-based OTLP receivers under "Setup > Telemetry > OpenTelemetryCollector" was enhanced to allow the selection of default socket addresses to listen on. However, the migration of existing 2.5.0 configurations was not properly applied, leading to a crash when viewing the configuration:
Internal error: 'socket_address'
As a workaround, users could open the affected configuration and save it again. The running OpenTelemetry Collector was not affected by this issue, only the WATO configuration page.
With this werk the existing configurations are now properly migrated without needing the workaround.
