SearchUI issues with reverse proxy

Elastic Search
1

Hello,
I am using App Search instance and a user interface based on elastic SearchUi example. I am reverse proxying the node.js app and the connections to the App Search API with Apache2.
I cannot get this to work. I get the error message:
An unexpected error occurred: Cannot read property 'forEach' of undefined
I think this means that the search payload is not getting through but I am not 100% positive.

Hey @turekg,

Are you seeing that error in your node.js app, or in the browser?

It shows in the browser, I am assuming it's getting passed back from the server.

The relevant bit of my proxy setup are:

   SSLProxyEngine          On
    ProxyRequests           Off
    ProxyPreserveHost       On
    ProxyVia                Full

    Header always set Access-Control-Allow-Origin "*"
    Header always set Access-Control-Allow-Credentials false
    Header always set Access-Control-Allow-Methods "POST, GET, OPTIONS"
    Header always set Access-Control-Allow-Headers "Accept, authorization, content-type, Host, Origin, x-swiftype-client, x-swiftype-client-version, x-swiftype-integration, x-swiftype-integration-version"

    # Added a rewrite to respond with a 200 SUCCESS on every OPTIONS request.
    RewriteEngine On
    RewriteCond %{REQUEST_METHOD} OPTIONS
    RewriteRule ^(.*)$ $1 [R=200,L]

    ProxyPass           /    https://127.0.0.1:5000/
    ProxyPass           /api/    https://127.0.0.1:3200/
    ProxyPassReverse    /    https://127.0.0.1:5000/
    ProxyPassReverse    /api/    https://127.0.0.1:3200/

Can you inspect the API request in the browser's Network panel and see what the payload looks like in the response?

The url is https://fiji-search.mpi-cbg.de/, and it is probably simpler if you inspect yourself.

Your API request is returning a text/html webpage:

<!doctype html><html lang="en"><head><meta charset="utf-8"/><meta name="viewport" content="width=device-width,initial-scale=1,shrink-to-fit=no"/><meta name="theme-color" content="#000000"/><link rel="manifest" href="/manifest.json"/><link rel="shortcut icon" href="/favicon.ico"/><title>Gitter Search</title><link href="/static/css/main.0ac613d8.css" rel="stylesheet"></head><body><noscript>You need to enable JavaScript to run this app.</noscript><div id="root" class="app-container"></div><script src="/static/js/main.2287eacc.js"></script></body></html>

OK, so where is it going wrong?

So the problem was in the order of the the proxy calls, argh!
