The error is coming from nos2x:

This might be nostr:nprofile1qydhwumn8ghj7un9d3shjtnhv4ehgetjde38gcewvdhk6tcpzdmhxue69uhhwmm59e6hg7r09ehkuef0qythwumn8ghj7enjv4h8xtnwdaehgu339e3k7mf0qyd8wumn8ghj7mn0wd68ytn5dpjhxctdv43kzapwd9hj7qgcwaehxw309ahx7um5wgh8x6tydekxzcnn9ehxctcqyqalp33lewf5vdq847t6te0wvnags0gs0mu72kz8938tn24wlfze65qkltc 's problem, at least because the error message is undefined. But I wouldn't rule out coracle passing something broken to nos2x.
