Create Case hangs when connecting to a new Endpoint for Vespa

[flaxsearch]

Describe the bug
I can send a search request to Vespa using cURL and a custom authentication header and get results back. So I try setting up a Custom Endpoint using the same URL and header details, but when I try to select this in a new Case it just hangs at the "What Search Endpoint do you want to connect to?" screen - you can't continue to create the Case and have to kill it. Trying the 'Ping it' option doesn't work either.

To Reproduce
Set up a new Endpoint with a URL like this:

https://xxxxxxxxx.vespa-app.cloud/search

and Custom Headers like this:

Authorization:Bearer vespa_cloud_xxxxxxxxxxxxxx

Save the Endpoint as usual. Create a new Case and attempt to select the new Endpoint.

Expected behavior
Should proceed to the next step of creating a Case, but it hangs and you can only close the new Case.

Interestingly it works without the Custom Headers being entered when the Endpoint is created, e.g. the Case creation doesn't hang. Adding them in later to the Endpoint seems to work too. So it's only a problem when the Endpoint already contains custom headers and you then create a new Case.

[flaxsearch]

This may be because it seems Custom Headers have to be in JSON format e.g.

{ "Authorization" : "Bearer vespa_cloud_xxxxxxxxxxxxxx"}

Will raise a separate issue to make this clearer, but the Create Case screen should still not fail in this way.

thanks... So, did you have the custom header in the Search Endpoint? Right now the mapper I think doesn't take into account either anything like a custom header...

So, if you could spin up a vespa that I could bang against, I can make sure that with the bad custom headers, we don't have it hang... I need to figure out how to duplicate the siutation you have...
