Facing issue while using tRestClient Component

SSharma1993 — Fri, 15 Nov 2024 22:58:33 GMT

Hi,

I am trying posting a JSON through tRestClient component. Below are the parameters which i have set in component settings:

HTTP Method: POST, Content Type: JSON, Accept Type: Any

Input Schema: Repository (Json metadata)

Request is based upon Bearer Token so selected OAuth2 Bearer and provided the token value.

Did not give any query parameter and HTTP Headers.

Talend version - 8.0.1

java - zulu 17

Please help!

Error as below:

Starting job API_testing at 12:47 29/04/2022.

[statistics] connecting to socket on port 3452

Hi, you can try to set no auth and add a header named "Authorization"

with value : "bearer yourtokenhere".

eg:

Header name :

"Authorization"

Header value :

"bearer 1456465456121545d54"

Send me love and kudos

Thankyou for the response!

I tried that and now it gives there is an issue with JSON file. However when I validate it in JSON viewers, it seems to be correct.

Below is the job output and JSON format I am using:

| tLogRow_3 |

|=--------+-----------------------------------------------------=|

|errorCode|errorMessage |

|=--------+-----------------------------------------------------=|

|400 |{"code":400,"message":"Invalid json message received"}

{

"identifier": "123",

"enabled": true,

"family": "AC",

"categories": [],

"groups": [],

"parent": null,

"values": {}

}

I think you need to check what JSON message format is expected by API, try this JSON string with other client tool such as Postman.

you have to use a tWriteJsonField with one column output named string to the tRestCLient

Hi,

Could you please send me a link or doc to refer for giving JSON as context variable or input parameter to tRest component instead of hardcoding it in HTTP Body.

you just have to connect the tWriteJSONFields component to the tRestClient component with a main link and in the tWriteJsonFields you just have one field in the Output named string of type String.

So, as my tWriteJSONField component is not giving desired results. I will try reinstalling Talend and then try to access it using jdk 11
