Error serializing value when using Avro Union schema about xk6-kafka HOT 2 CLOSED

Hello @mostafa ,

Thanks for the quick reply. I believe I had tried that approach, in any case, I just tried it again, and it fails for the same reason (panic because of the nil pointer). Debugging through the code, the error message I get is the following (same as before):

Union item 1 ought to be valid Avro type: unknown type name: "test.ProductCreated"

Given the goavro question you referred to is > 5 years old and hasn't been addressed yet, I guess chances to see it addressed are not that high. In any case, we have worked around the problem, but wanted to see if there was a way to fix it.

Thanks!

Hey @ehardy,

This seems to be a limitation of the goavro library, as raised here, yet I suppose you can make it work using a combination of the schema subject and the data, which is roughly like this, or something along the same lines:

const value = registry.serialize({
    data: { "test.ProductCreated": {
        id,
        productName: 'test',
     },
    },
    schema: schema,
    schemaType: SCHEMA_TYPE_AVRO,
});
