Influxdb 2.0.0-beta.12 with nginx reverse proxy

[jaysnm]

First and foremost I thank Influxdata team for their sparkling products, in particular influxdb and telegraf. While trying the beta version of influxdb I encountered an error creating dashboard. I repeated create dashboard from template three times. All failed with service unavailable errors. I logged out, cleared browser data and logged back. Cards of the the three dashboards I created showed. Opening any of them printed below errors. My Telegraf is properly configured for both input and outputs.

Browser UI and logs

I'm using quay.io/influxdb/influxdb:2.0.0-beta image Influx CLI 2.0.0-beta.12 (git: ff620782eb) build_date: 2020-06-24T21:45:25Z

I also wonder milestones made towards issue #15721 . I followed issue #5352 which led me to this gist. Using the gist, I configured the server as below resolving all requests to /influxdb/.

http {
  [....]
  map ... [ ...]
}
location /influxdb/ {
        proxy_pass http://localhost:9999/;
        [.....]
  }

{I think} all static files resolved and /api/v2/flags. I expected to see api/v2, api/v2/setup and /signin in network logs.

What could I be doing wrong here? My working set-up uses / and not /influxdb/
Thanks in advance.

@jaysnm thanks for the issue. Sorry for the delay in responding. Is this still an issue with beta-15?

Thanks @russorat for reverting. It's no longer an issue.
