Hey @ErnstIngmar

Your request/response would be very specific to your context - We're going to be unable to recreate this same behaviour, given the steps you have provided as it wouldn't be the same for any request being sent from Postman.

Can you update the issue and provide more details about the request that you're sending and the response message that you were expecting to see returned, please?

[ErnstIngmar]

Steps To Reproduce

I want to check all the server mesasges be returned correctly , when the specific value in body is wrong or not surport in your api.

1. Open a new request tab
2. In the request body, set one value be wrong data, which your api don't surport, Then Send the request
3. See the response tab view
4. See error message: Parse Error: Response overflow —— > here , the server had returned detail error messages, I can see the returned values from jMeter, but I can't see it in postman.

I guess, this just a similar bug like "Parse Error: Header overflow"

[DannyDainton]

What is the returned value you're expected to see in Postman? That request is very contextual to your server.

Can you provide an example of what's returned in Jmeter?

If I make the same request to say https://postman-echo.com/post I'm not going to see that error because it's not going to your server.

[ErnstIngmar]

When I send a post request with body { "id": null}, set id value to be null,.

My server return the error message: "Param [id] is Empty", I can see this message in JMeter correctly.

But Postman just returned "Parse Error: Response overflow" , not the correct message .

It's not the correct message from the server. just an error from postman.

@ErnstIngmar,
Sorry for the late response, we are unable to reproduce this error with the information that you have provided. Can you provide us with a demo server code (zip file) that can reproduce this error, so that we can look into this further?

[ximki]

if I return a StatusCode(MyCode,MyError) from my Api it shows the same error "Response overflow", you can reproduce the issue as easy as that :)

[dev-sharma-08]

@ximki, Can you help us with how are you sending this to API, and what does this function StatusCode do? It would be helpful if you could provide a sample code for your server excluding any sensitive information.

[ximki]

StatusCode is a method of AspNetCore.MVC.baseController
it was problem with the api implementation I think, because tried with another API and it returned the result as expected with the status code and error description :)

[dev-sharma-08]

@ximki, I am glad to know that it worked. For now I am closing this issue, feel free to open this if you encountered this issue again.
