Influx generating invalid configs

Telegraf
,
1

I am trying to set up a vSphere connector, but InfluxDB is generating invalid configs that Telegraf is rejecting. I am getting this error:

2025-10-14T13:48:58Z I! Loading config: http://lol.no
2025-10-14T13:48:58Z E! loading config file http://lol.no failed: error parsing data: line 128: invalid TOML syntax

Here is a the part of the config file downloaded directly from Influx:

  ## Optional TLS Config for use on HTTP connections.
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false
-# Read metrics from one or many vCenters
[[inputs.vsphere]]
  vcenters = [ "https://lol.no" ]
  username = "nothappening@lol.no"
  password = "Password12345"

Line 128 that itā€™s complaining about is [[inputs.vsphere]]How is this fixable if I have no control over the final file generated thatā€™s seemingly much different than the file that I edit in the setup process to add credentials for vSphere?

Where did you get this from? I donā€™t think the dash in front of

-# Read metrics from one or many vCenters

is anywhere on our docs, is it?

Thatā€™s from the config file that is generated from the ā€œcreate configurationā€ wizard. That dash is there in the ā€œstockā€ file. If that dash is an issue I can regenerate the config using the wizard and remove it since I do see it here on line 1.

So thatā€™s in InfluxDB isnā€™t it? @suyash do you know anyone who can look at this?

@Ryanhaku please try to remove the dash in front of the hash and check if this fixes the problem!

Well, that seems to fix it.

Yes, that is indeed very strange and perhaps a bug that needs to be fixed. @Ryanhaku glad you were able to resolve it manually, mind give me the steps to reproduce the problem so I can file a bug or you can directly do it here: GitHub Ā· Where software is built Thanks!
