Yes, I tried again and it worked.

I get that sometimes too with NWC. Even my custodial nostr:nprofile1qqsyv47lazt9h6ycp2fsw270khje5egjgsrdkrupjg27u796g7f5k0spzemhxue69uhk2er9dchxummnw3ezumrpdejz7qgwwaehxw309ahx7uewd3hkctcprdmhxue69uhkummnw3ez6vfwde3x7tnpdenkzmnf9e3k75xqss4 wallet did it. An immediate follow up attempt to zap usually works so I don't think it is a channel balance issue.
