MessagePack queries: Exception during parsing InfluxDB version [macOS]

[bednar]

Hi @lxhoan,

I want to try the MessagePack queries at macOS but there is a bug in parsing InfluxDB version. On the macOS the version of InfluxDB is in a format v1.6.0 so parsing of the version fails.

The InfluxDB was installed by brew.

I also created a simple test so you can reproduce it.

The InfluxDB ping response on macOS
