• Create a test network
• Have 2 accounts with +1M sats

• Attempt to pay
• See insufficient_balance error

I would expect the invoice to be paid

The balance you see there is the on-chain wallet, not the balance on lightning. It looks like you havent created any channels yet. You have to open channels between the nodes in order to make a payment between them.

Check out the video on https://lightningpolar.com to see a walkthrough of opening channels and making a payment.

thanks @jamaljsr 😄 I will check it out and comment back here. When I solve it I'll close the issue. I think a few people new to blockchain development will find this conversation helpful

@jamaljsr setting up the channel was the issue, thank you very much!

On the other hand, the slack invite seems expired on the official website, how could I have an invite please? I am developing a lighting app and I'm struggling to find community support in general

[jamaljsr]

Where is the broken Slack invite link? I'd like to fix it.

Unfortunately, the invite links provided by Slack have an expiration on them. You should always be able to find the working link on the https://lightning.engineering/ website.
