SAP Cloud SDK executeHttpRequest Request failed with status code 407

[WouterLemaire]

Hi all,

I'm trying to use the function "executeHttpRequest" of the cloud SDK to create a request to my on premise backend system like this:

const token = retrieveJwt(request);
return await executeHttpRequest({destinationName:"MyDestination",jwt:token},request)

Unfortunately this results in a 407, which means my proxy authentication is missing. But when I get my destination before sending the request, I notice that the proxy authentication is available. I do this by using the following function:

const destination = await getDestinationFromDestinationService("MyDestination",{userJwt:token})

Any idea what I'm missing?

Here you have the full log from the request till the 407 error:

I'm also wondering why this shows up in the log "Unable to match a specific XSUAA service instance to the given JWT...." When looking at the decoded token and comparing it with the bound xsuaa service, it looks the same..

Thank you in advance!
