I have a rest endpoint which reads the request body and is mapped to Java POJO.
The issue I am facing is I get the below exception when I send the request as a GET. But the exception is not thrown when I change the type to POST and request succeed.
@Path("/test")
@GET
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public Uni<List<String>> getData(ReqeustBody requestBody) {
//app code
}
My thought is that jackson library that does the mapping of request body to pojo is causing the exception. But why it fails only for GET and not for POST.
Any leads will be of help.
Below is the stack trace.
