Zendesk Secure Settings Proxy Error

We're using Zendesk's Secure Settings feature to inject our private API token into our Zendesk App. We are seeing "Proxy Error: Invalid Response" when we make a call to our API through the Zendesk Proxy (which is injecting the secure setting private API token). Our theory is that the Zendesk proxy is adding headers to our request, headers that our API doesn't allow.
 
Is this an error with the request that our Zendesk app sends to the Zendesk proxy or is the error from our API when the proxy sends the request to our API? Does the Zendesk proxy add headers to the request to our API?
 
I've included screenshots of the response and our snippet of code making the call

    Hey Kate,

    Tough to say based on the info we have. Are you experiencing this when serving the app from local during development?

    Thanks!

    Hi Eric,

    Yes I'm experiencing it while running the app locally using:

    zat server --app-id=

    with our app id & then entering our private API key when prompted by:

    Enter a value for optional parameter 'lomi_api_private_api_token' or press 'Return' to skip:

    Is the Zendesk proxy adding headers to the request?

    Hey Kate, 
     
    Zat can't actually handle secure parameters when running the app locally. We talk about it here and here, I'd suggest installing the app as a private application and see if you still run into the issue. 

    Thanks!

    Hello Kate,

    can you try cors: true option in request for making  cross-origin HTTP requests 

    Thanks,

    @eric27 That explains a lot! I hadn't come across that yet, thank you!
    That's a bit frustrating that we have to deploy in order to test but that unblocks me!

     

    @dinesh11 cors: true can't be used with Zendesk Secure Settings because it cors: true bypasses the Zendesk Proxy which is what injects the Secure Setting.

    I am having this same problem. Were you able to resolve it? It seems like the error is on the Zendesk proxy server, not the external API server.

    Hey Brian, 

    Are you experiencing this when testing from locally while using secure settings like Kate?

    Hi Eric,

    No, I had noticed from the documentation that secure parameters cannot work through the ZCLI testing method, so this was after uploading to our environment.

    Thank you,

    Brian

    Hey Brian,

    Would you mind if we open up a ticket so that you can share your application with us?

    Thanks!

    Hi Eric,

    Figured it out! The domainWhitelist in the manifest was incorrect. I had only added "domain.com" and it requires "subdomain.domain.com." That one change fixed it.

    Thank you,

    Brian
