This exact shape hit us building NOSTRAS's zap support — most zap-request builders (we used NDK) append a malformed empty NIP-10 marker to the e tag by default. Most LNURL providers silently tolerate it, but Alby's validation is strict and rejects it outright — which lines up with you running your own node behind Alby specifically. Worth checking if it's always the same sending client failing, not random — if so, that sender's zap-request shape is the likely culprit, not your setup.
