Empty event handler results in Error 400 Bad Request

General
1

If I generate a before or after create handler, and don’t add any other code, all create requests return an error 400 Bad Request.

2

Do you run the handler in the debug mode or in production?
Is it a “catch-all” handler or for a specific table?

3

Everything works in local debug mode, but I only get errors when I deploy anything. I generated a brand new empty handler and its also returning error 400. Its for a specific table.

4

Is it possible for you to share your table’s generated class?

this?



@Asset( "Comment" )
public class CommentTableEventHandler extends com.backendless.servercode.extension.PersistenceExtender<Comment>
{


    @Override
    public void afterCreate( RunnerContext context, Comment comment, ExecutionResult<Comment> result ) throws Exception
    {
        // add your code here
    }


    @Override
    public void beforeCreate( RunnerContext context, Comment comment) throws Exception
    {
        // add your code here
    }


}

Oh, no, I mean your Comment.java class, it should be in “models” package.

I just deployed a no-op “create” event handler and tried a few REST requests to add data objects. It worked as expected. Could you try adding an object using the REST Console? It is available on the Data screen (there is a separate tab there). You will need to enter a JSON object into the Request field and click the POST button.

This is what I get, it doesn’t show headers or status code, but its the same response Im getting with 400:

{
“message”: null,
“code”: 0
}

Could you please let me know your app id?
