Errors calling databricks rest api /api/2.1/jobs/run-now with job_parameters

[ErikJ]

Hello! I have been using the databricks rest api for running workflows using this endpoint: /api/2.1/jobs/run-now. But now i wanted to also include job_parameters in my api call, i have put job parameters inside my workflow: param1, param2, and in my call to the api im sending this:

params ={"job_id" : 12312312

"job_parameters":{"param1":"12",

"param2":"test"},}. But for some reason i get following response:  {'error_code': 'MALFORMED_REQUEST', 'message': "Could not parse request object: Expected 'START_OBJECT' not 'VALUE_STRING'\n at....

Anyone knows what the problem may be? Ive also just copied the sample request as specified in documentation:https://docs.databricks.com/api/azure/workspace/jobs/runnow#job_parameters but its not working either.

Hi @ErikJ ,

Are you sending a POST request to the /api/2.1/jobs/run-now endpoint? It's important to use a POST request because this endpoint expects the parameters to be included in the request body as JSON, not as query parameters.

Also, your "params" seem malformed, with a missing comma after "job_id": 12312312 and an extra comma after "job_parameters". This might just be due to copy-pasting, but incorrect JSON formatting can cause the MALFORMED_REQUEST error you're seeing.

Here's how your JSON body should look:

{
  "job_id" : 12312312,
  "job_parameters":
  {
     "param1":"12",
     "param2":"test"
  }
}

 Additional Notes:

• Ensure Correct HTTP Headers: Make sure you're setting the Content-Type header to application/json in your POST request.
• Validate Your JSON: It's a good idea to validate your JSON payload using an online JSON validator to catch any syntax errors.

{
    "job_id": ,
    "job_parameters": {
        "params1": "",
        "params2": ""
    }
}

Yes my bad maybe, but it is correctly formatted, and im using POST exactly as described in the databricks rest api documentation. I even copied their example json but that didn't help. I just know that, i can run the job using api, but as soon as i add parameters inside "job_parameters" i get this in return. But I will look into it today!
