Swagger claims receive endpoint returns string, but it's an object

[crummy]

The problem

I ran the liblab API generator against the swagger code with:

liblab init --spec https://bbernhard.github.io/signal-cli-rest-api/src/docs/swagger.json
liblab build --language java

(I had to fix the /search endpoint missing {number}, but after that...)

When I call the /v1/receive endpoint, I get this error in my client:

com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize value of type `java.util.ArrayList<java.lang.Object>` from Object value (token `JsonToken.START_OBJECT`)
 at [Source: (String)"[{"envelope":{"source":"+178...","sourceNumber":"+1781...","sourceUuid":"...","sourceName":"...","sourceDevice":2,"timestamp":1732652479395,"dataMessage":{"timestamp":1732652479395,"message":"...",...

The function func (a *Api) Receive(c *gin.Context) does seem to return a string, rather than a JSON object. But presumably it's a JSON string, returned from the client.

I think the fix would be to, in signal-cli-rest-api, parse the returned string into an object, return it with c.JSON(200, obj), and add the object type to the swagger comments. Does that sound right?

Thanks for the report!

yeah, right. It is on my todo list since a while, but I haven't found time to work on that.
