Kibana doesn't see the indices

Hi there. I've been experiencing a problem with Kibana - the indices don't show in index patterns menu even though all the indexes are present in index management menu.

The whole thing runs under proxy.
{ "took": 833, "timed_out": false, "_shards": { "total": 4, "successful": 4, "skipped": 0, "failed": 0 }, "hits": { "total": { "value": 10000, "relation": "gte" }, "max_score": null, "hits": [] }, "aggregations": { "indices": { "doc_count_error_upper_bound": 0, "sum_other_doc_count": 0, "buckets": [ { "key": "logs-64cb0a97d4594f79bf2b2a5bfd9763e1-2019-08-01", "doc_count": 185111 }, { "key": ".monitoring-es-7-2019.08.01", "doc_count": 201 }, { "key": ".monitoring-kibana-7-2019.08.01", "doc_count": 24 }, { "key": ".kibana", "doc_count": 2 } ] } } }

Do you see the same problem if you bypass the proxy?

without proxy
curl -d'{"size":0,"aggs":{"indices":{"terms":{"field":"_index","size":200}}}}' -H 'kbn-xsrf: reporting'
{"statusCode":500,"error":"Internal Server Error","message":"An internal server error occurred"}

Elasticseach and Kibana - both 7.2.1

Can you bypass the proxy and access Kibana? How is the proxy set up?

if I set rewriteBasePath to true, everything's accessible outside proxy and I can see all of my indices.
Otherwise it's not accesible - I'm getting such errors:
Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'unsafe-eval' 'nonce-WlAeJVZ1TIIKfZ8U'". Either the 'unsafe-inline' keyword, a hash ('sha256-SHHSeLc0bp6xt4BoVVyUy+3IbVqp3ujLaR+s+kSP5UI='), or a nonce ('nonce-...') is required to enable inline execution. bootstrap.js:1 Failed to load resource: the server responded with a status of 404 (Not Found)
Proxy is basically rewriting the link, removing basePath, packing headers and sending a request via Python urllib.request.Request.

btw, in 7.3.0(both es and kibana) error looks like that:
Uncaught (in promise) Error: Loading chunk 169 failed.

If it ever helps anyone, the issue was resolved by adding Content-Type": "application/json" to the headers of the request. Good luck everyone!
