JsonFormat deserialization with custom extensions

[PlugaruT]

Hi, I'm using JsonFormat to deserialize a JSON string into a CloudEvent. Example below:

...
String dataJson = afterJsonNode.get("data").asText(); // this is how I get the json string

JsonFormat jsonFormat = new JsonFormat();
CloudEvent e = jsonFormat.deserialize(dataJson.getBytes());

Seems that if the string has a custom extension, it fails on deserialization with

Caused by: com.fasterxml.jackson.databind.exc.MismatchedInputException: Invalid extensions name: ce_sourceid

Any idea why? Should the library pass the custom extensions further?

Thanks

Seems that the extension name was not respecting the spec. It should not contain special charts. In my case it should be sourceid, without _. My bad.
