Issue in service template creation, defining new node properties

[ameyverse]

Hi, I had some issues in using the winery interface.
I tried the opentosca/winery:latest image with below environment settings

docker run -it -p 8080:8080
-e PUBLIC_HOSTNAME=localhost
-e WINERY_FEATURE_RADON=true
-e WINERY_REPOSITORY_PROVIDER=yaml
-e WINERY_REPOSITORY_URL=https://github.com/radon-h2020/radon-particles
opentosca/winery

1. The UI shows 400 OK error while adding new properties in a custom defined node type. The container logs during the operation are as follows:

54 > POST http://10.15.8.148:8080/winery/nodetypes/example.org.tosca.nodetypes/CustomNode_w1-wip1/propertiesdefinition/
{"winerysPropertiesDefinition":{"namespace":"example.org.tosca.nodetypes","elementName":"CustomNode_w1-wip1","propertyDefinitionKVList":[]},"selectedValue":"Yaml","propertiesDefinition":{"element":null,"type":null,"properties":[{"name":"os","type":"string","description":"","required":true,"defaultValue":"","status":"supported","constraints":[]}],"propertyDefinitionKVList":[]}}

10:10:53.898 [http-nio-8080-exec-6] INFO  o.g.jersey.logging.LoggingFeature       :149  log                                 - 54 * Server responded with a response on thread http-nio-8080-exec-6
54 < 400

Expected YamlPropertiesDefinition element

2. I tried to create a topology template through REST API (PUT /servicetemplates/com.test/TestAppTopologyTemplate_v1-w1-wip1/topologytemplate) with the json payload of an already created template (through UI) with a couple of nodes and requirement relationships between them.

The nodes are properly created in the new service template TestAppTopologyTemplate_v1-w1-wip1, but the relationships are not visible in the UI.

Kindly guide in resolving the issue. @lharzenetter @wederbn
Thanks.
