In the log file we have detected a "400 Bad Request" error entry due to an incorrect request when "reloading" the associated service metadata into the data-metadata. Distributions are often created from the service metadata and added to the metadata. If the service metadata cannot be read, distributions cannot subsequently be created from it.
The reason for the "400 Bad Request", was a URI with an umlaut in combination with the wrong encoding, ISO-8859-1 instead of UTF-8. It seems that the default behavior of the HTTP client used changed with the upgrade of Apache Camel from version 2 to version 3.
In the affected request the character "ß" in the word " Straßenbeleuchtung" is the problem.
The ISO metadata with the problematic value in "MD_Identifier" can be retrieved from the link https://gdk.gdi-de.org/inspire/srv/eng/xml_iso19139?uuid=fa00f154-4459-48d4-87b2-fcbd14e7a91f.
Steps to Reproduce:
a) Enter the CSW interface of the GDI-DE in the configuration.

/omdf/gp-csw?verb=GetRecord&identifier=fa00f154-4459-48d4-87b2-fcbd14e7a91fThis PR explicitly specifies "UTF-8" as the encoding in coupled services route for the service metadata reload query.
