Data sources configuration crashes

Grafana

> Hi,
> Pretty new in that field, I'm installing Grafana v8.1.2 (103f8fa094) on rhel 7, to use it with influxdb.

When I want to configure a "data sources" it returns "TypeError: e.dataSources.filter is not a function"; with additional errors like "at E (.../public/build/vendors~app.8ea303538f79ee32b68a.js:2:73696) "

Hi @juliensorel,

Ok, so you are running Grafana on RHEL behind nginx, yes? And you can access Grafana through your browser without issues, yes? Are you running influxDB on the same instance and querying it on localhost? What does your datasource configuration look like?

Hi
All points are correct. Influx is on the same instance. It’s not possible to configure any datasource. Yielding d.filter is not a function.

can you communicate with influx using cURL? Just want to establish that communication is possible…
