Can't fund wallet through just in time channel

[holzeis]

On regtest we get regularly no route issues due to no hop data found errors. This seems to happen not deterministically, meaning that sometimes it works right away and sometimes it doesn't.

The assumption is that upon opening a channel a node announcement of some sorts needs to happen for the payment to get successfully routed.

This is very likely also the issue that our onboard_from_lnd is failing every now and then.

Related to #774

Note, in production this issue seems to be solely related to our liquidity or connectivity, so I think this is only a regtest specific issue.

All end-to-end tests use the funding step now on regtest, let's monitor whether they fail at all due to this issue - I will update it if I spot any failures due to this reason.

I managed to replicate the issue for no_route when paying an invoice after the funding (see: #880 )

From #999:

This consistently fails on an android emulator for me. Invoice is still payable manually using the faucet.

Does it work for you natively?

Yes, it does. It only appears to be an issue when running on the android simulator. I can test the physical phone too if need be @da-kami already said it doesn't work for him there

Very interesting. Thanks for sharing.

@Restioson can you check the nodeinfo on the lnd node? Is synced_to_graph true?

How would I go about doing this?

[Restioson]

In my case, it actually was an android setup issue, since in android the REGTEST_FAUCET environment variable is not set up correctly
