❯ go-networkmanager-qrcode-generator -l
the following connections are known:
Got 37 connections

I thought it would output the connection names ^^

And the content is also empty:

Using networkmanager with plasma-nm if that matters.

That's indeed a bit wrong. For me -l indeeds prints some lines with

<name of the connection in network manager>:    SSID <the ssid spelled out>

The number of printed lines is also for me smaller than the printed number (37 for you) for the following reasons:

the number of connections i quote is just number of network connection that network manager shares over dbus. but that's not just wifi connections, it also counts ethernet or bridges. Which is why the 37 is probably a bit inflated with respect to how many wifi connections you actually have.
Even for wifi connections, I only generate QR codes for connections that I know how to encode / found in the documentation. I.e. I WPA Personal and WPA2 Personal should work, but WPA Enterprise or WPA2 Enterprise will fail.
On top of that I don't know if there can be permission issues (I expect on a multi user device where one user creates a connection but doesn't allow other users to use the connection,).

Obviously I assume you are running on a device with wifi connections. Could it be none of them is WPA/WPA2 Personal or WEP?

Beyond these guesses I'm afraid there's not much debug output I added that would help us narrow down why your connections come out empty.

Have you tried with the tui?

go run github.com/pseyfert/go-networkmanager-qrcode-generator/tui

OR

I recently discovered https://github.com/kokoye2007/wifi-qr which aims to provide the same functionality. I'm curious if that works for you. Those potential issues i listed should be the same as for wifi-qr but if that works for you, you at least get your qr codes, and we have a hint that the issue is something my tool should be able to handle

https://github.com/dlenski/wifi2qr worked fine, I usually use WPA2-PSK
