Local mode - Service bindings loaded twice - Cannot get destination

[cgaillydetaurines]

Hi Colleagues,

I am trying to run my application locally but I cannot reach destination service because bindings are loaded twice from my "default-env.json" file, and DestinationServiceAdapter class does not accept having several bindings.

In the ServiceBindingMerger, the bindings are doubled:

My supposition is loaded first by SapVcapServicesServiceBindingAccessor class

And a second time by VcapServiceParser from cap.

Appreciate your help, Clément.

What does your local environment variable look like? VCAP_SERVICES

What does the local CAP env file look like? default-env.json

Please hide any unrelated / sensitive data.

Hi Alexander:

I have no VCAP_SERVICES env var setup on my machine.

My default-env.json:

If needed, we can setup a call, I can attach easily a debugger to my env.

Tx, Clément.

I have sent an MR for 27th June for a screensharing session.

After screensharing, investigation and discussion also with CAP, we concluded:

cds bind shall not be used in combination with default-env.json

Please approach CAP colleagues directly for a suggestion on how to start the application then.

Context:

• At runtime a duplicate service binding was found for "destination" service. According to SAP Cloud SDK, this is unexpected.
  • DefaultServiceBindingAccessor.getInstance() shows (among others) the following loaders, each returning equal entries for "destination":
  • DefaultEnvFileServiceBindingLoader yields data via default-env.json.
  • SapVcapServicesServiceBindingAccessor yields data via System.getenv("VCAP_SERVICES").
    • Presumably using cds bind when running the application results in environment variables being populated. Thus the information is loaded twice. This leads to an error.

Suggested workaround (may not be used for production):

```java final List accessors = ServiceBindingAccessor.getInstancesViaServiceLoader(); accessors.removeIf(accessor -> accessor instanceof SapVcapServicesServiceBindingAccessor); final ServiceBindingMerger bindingMerger = new ServiceBindingMerger(accessors, ServiceBindingMerger.KEEP_EVERYTHING); DefaultServiceBindingAccessor.setInstance(new SimpleServiceBindingCache(bindingMerger)); ```
