modbus input plugin sample_metric.conf contains malformed toml syntax

[cwedel]

Use Case

I wanted to parse the modbus sample config that was exported with Telegraf config create. To edit this in general way.

Expected behavior

I could parse the toml input config file without any errors.

Actual behavior

I tried to parse the config file. But add the metric section from the modbus input plugin. I get the error of a malformed toml syntax. This error appears on line 62 col 68 in that comes from the file "telegraf/plugins/modbus/sample_metric.conf".
The toml lint checker also says the there is an error. For me its seemed like a typo. Because there is only an ',' to much.

Additional info

No response
