ERROR detecting boards: error getting board info from Arduino Cloud

[mkovalevski]

I run arduino-cli in my React app and when I tested app without network i got this message:

Error: Command failed: .\extra\arduino-cli.exe board list --format json
Error detecting boards: error getting board info from Arduino Cloud

I want my app work without network. How can I download board info and work with it offline?

I have reopened this because the bug is not resolved.

To reproduce

1. Disconnect your computer from the Internet.
2. Run the command arduino-cli board list

The command fails and no ports are listed:

$ arduino-cli version
arduino-cli.exe  Version: nightly-20220125 Commit: 23e7cb5 Date: 2022-01-25T01:29:37Z

$ arduino-cli board list
Error detecting boards: Error getting board info from Arduino Cloud

$ echo $?
5

It is reasonable to print a warning that it could not collect the supplemental convenience information by querying Arduino's online database. However, there is no reason this should cause the command to fail to list the ports and the board identifications from the data of the installed platforms.

Upon further examination, I have noticed the following:
if a user has multiple boards connected, one of which with a resolvable fqbn via means of installed boards.txt, and the other which cannot be resolved unless the CLI is able to query the service, even the normally recognised one will be skipped and CLI will generate an error and even break the JSON output.

I'll be analyzing the following scenario

Besides the Nano RP2040 Connect not being recognised when an unrecognisable board is part of the set,
the JSON formatting is now broken, rendering any chance of parsing impossible
