I am getting the following exception while trying simple code from docs.
Cannot find serializer for value ‘ObjectValue [value={001=Notebook, 002=Server, 003=Workstation}, isDeserialized=true, serializationDataFormat=application/json, objectTypeName=null, serializedValue=null, isTransient=false]’

here is the code snippet:

Map<String, String> productTypes = new HashMap<String, String>();
productTypes.put(“001”, “Notebook”);
productTypes.put(“002”, “Server”);
productTypes.put(“003”, “Workstation”);

    execution.setVariable("AVAILABLE_PRODUCT_TYPES",
            objectValue(productTypes)
                    .serializationDataFormat(Variables.SerializationDataFormats.JSON)
                    .create());

pom.xml (2.9 KB)

Hey @rahulnanda24 ,

looks like Spin is not properly initialized. Have a look at Configuring Spin Integration | docs.camunda.org to see what you need to add to your pom.xml.

From a first look, I think you might be missing the spin-core artifact.
You can also go along with the Spin Engine Plugin and Dataformats All artifacts where this is all packaged for you (but also slightly larger of course and including XML, which you might not need).

Best,
Tobias
