Error during request to remote service: \nread ECONNRESET in CAP OData Service

[Phani_Kumar]

Hello Experts,

I am trying to reach an both S4 On Premise OData and BW On Premise OData systems from CAP Service. I am able to reach S4 Successfully but not BW Service.

I am getting "Error during request to remote service: \nread ECONNRESET" when doing the testing from Local. Is there something that I am missing out

I can see call is successfully routed to the right destination but I don't find any logs of this service hitting either Cloud Connector or BW System.

Hello!

I encountered the exact same issue, and the only solution I found was through using "Storyboard". Instead of importing the .edmx file and configuring it, I simply added a new external resource via the storyboard visual tool (using the "Open Storyboard" command). This method unexpectedly listed all services and entities without any problems. Additionally, I configured the development destination by adding it to the "default-env.json".

This situation is peculiar because, beyond just listing services and entities, the curl test with the specified destination also worked. The SAP Knowledge Base Article 3112360 - 502 error connecting to backend OData from CAP project in BAS wasn't particularly helpful. Even after completing all the necessary configurations, I still had to use the "cds watch" command, otherwise I would have binding issues.

If you, or anyone else for that matter, discover another method to resolve this issue, please let me know.

Best regards,

Rafael

Hi gallaphanikumar ,

When testing locally, BAS connects to onPrem via CC using a proxy.

In your project, create an .env and add the following info to test.

The .dest is mandatory as BAS figures the destination info accordingly.

[

{

"type": "HTTP",

"name": "<DESTINATION-NAME>",

"url": "http://<DESTINATION-NAME>.dest",

"ProxyHost": "localhost",

"ProxyPort": 8887

}

]

To enable logging of the remote service, you can configure the environment variable DEBUG=remote. For example:

DEBUG=remote cds watch

Hi arley.trianamorin ,

Thanks for your response. I have enabled debug mode and got more or less similar info . Is there any other place where I can check out detailed logs? Can you please help me what could be the potential issue from the below log ?

Reaching BW On Premise is happening through basic authentication and reaching S4 On Premise is happening through Principal authentication. Do you think that could be a problem? Please advice

Exporting the following environment variable would display more detailed logs for remote services:

export SAP_CLOUD_SDK_LOG_LEVEL=silly

[Arley]

For Cloud Foundry, use the following command to set the environment variable for your application:

cf set-env <your_app> SAP_CLOUD_SDK_LOG_LEVEL silly

[Arley]

kubectl set env deployment <your_deployment_name> SAP_CLOUD_SDK_LOG_LEVEL=silly
