Error during the registration of a data plane instance

[boxer-code]

Hello everyone! I don't know whether this is a bug or an error in my configuration but I'm trying to combine the transfer-sample-06 with the data-plane kafka extension and after adding the extension, the following error occurs:

Is there an explanation for this behavior, or is it indeed a bug?

Could you give some more context?

[boxer-code]

Sure! I've taken the whole configuration from sample transfer-06-consumer-pull-http and copied the whole folder with the "data-plane-kafka" extension and the "spi" folder from the connector repo folder to the sample repo folder. To add the extension to the connector, I've added the following lines in the build.gradle.kts file from the http-pull-connector folder.

 implementation(project(":data-plane-kafka"))
 implementation(project(":spi:common:transform-spi"))

The connector is successfully starting and my expectation was that I'm able to perform the same curl-request from the example as before but the 404-error occurs.
The curl-request is the following:

curl -H 'Content-Type: application/json' \
     -d '{
           "@context": {
             "edc": "https://w3id.org/edc/v0.0.1/ns/"
           },
           "@id": "http-pull-provider-dataplane",
           "url": "http://localhost:19192/control/transfer",
           "allowedSourceTypes": [ "HttpData" ],
           "allowedDestTypes": [ "HttpProxy", "HttpData" ],
           "properties": {
             "https://w3id.org/edc/v0.0.1/ns/publicApiUrl": "http://localhost:19291/public/"
           }
         }' \
     -X POST "http://localhost:19193/management/v2/dataplanes"
