Getting 400 Bad request Error in trest client component

[Anonymous]

Hi,

When I was calling a http service using oauth Bearer token method of trestclient I am getting 400 service error but for the same url in postman I was able to retrieve the expected output.

How can I troubleshoot this issue or is there any other component apart from trestclient we can use for this.

Hi,
I tried in that way as well but I was getting the same error. Is there a way where we can get what request is been generated and sent. The same http url when I tried in thttprequest component it gave me a successful response but I want to retrieve the response headers which is not available in the thttprequest component.

Unfortunately I don't have access to the server logs to figure out what the issue was?

Hello,

You could access to your response header with tRESTClient.

((java.util.Map<String,java.util.List<String>>)globalMap.get("tRESTClient_1_HEADERS"))

Hi,

I get Error in trestclient for that particular request. The same request works well and good with thttprequest component.

The URL what I am trying to use will send the response in header which I can able to retrieve only in the trestclient not from the thtprequest component. I have attached the screenshots of the success response when I use thttprequest component and the Error response when using trestclient component.

@Sujay @xdshi 

I tried to sniff the request via Wireshark...

The generated request is:

GET /api/v1/Group/1245676456456/$export HTTP/1.1

Content-Type: */*

Accept: application/json,application/fhir+json

Prefer: respond-async

Authorization: Bearer yJ9

User-Agent: Apache CXF 3.1.2

Cache-Control: no-cache

Pragma: no-cache

Host: my.host

Connection: keep-alive

It looks like tRestClient currently has a setting of "Accept" with the default values as "XML"/ "JSON"/ "any". Since my endpoint requires "application/fhir+json", I add that as an additional header.

However, the endpoint accepts only one "Accept" parameter... "application/fhir+json". This is causing my request to be failed.

Is there any quick way to handle this by customizing the tRestClient? I am thinking if I can add a new ACCEPT; for eg: FHIR with the value as "application/fhir+json", it could help?

Can someone help with this?

Regards,

Bala
