SAP Data Intelligence - Deployed Pipeline API Call Error from postman and jupyter

[former_member704859]

Hello All,

I am getting an error in API call from Postman UI for my inference pipeline. Following are the steps I did:

1. Created an inference pipeline to read the data from HANA table and also accept the input from postman in JSON format

2. Deployed the pipeline in ML Scenario Manager as I want the pipeline to keep on running all the time. After the deployment, a REST-API URL is generated.

3. Copied the URL and made the API call from postman UI. It worked for few calls but then it suddenly starts throwing below error.

Illegal URL request path '/openapi/service/1381f941-8c02-477b-8679-57a07dcd9752/v1/uploadjson/'. No executing host found

4. I have stopped the pipeline, re-deployed it but still throwing the same error.

5. I also copied the 'Python-Requests' code from Postman and tried to execute it from Jupyter Notebook but still the same error.

Has anyone faced such intermittent issue? Any inputs would be appreciated as we are stuck due to this issue.

We raised this issue to SAP and after various checks done by them, it was concluded that this is a product issue in SAP DI 3.1 on-premise deployment. They have released a patch for DI cloud to fix the issue but patch for on-prem is yet to come.

We tested the same pipeline in their SAP DI cloud installation and it worked fine.
