expected json response, got "text/plain" - but with JSON response body

[andre-luiz-dos-santos]

I tried to test TimescaleDB by importing some data from InfluxDB, but the error below happens. The values in the response are what I have in InfluxDB. The only problem seems to be the Content-Type on the response. How to proceed?

influx version
Influx CLI 2.0.3 (git: fe04d346df) build_date: 2020-12-15T01:00:16Z

./outflux --version
Outflux version 0.2.0
Run 'outflux --help' for usage
