[ot][spam][crazy][junk][wrong] getting information onto a blockchain

[Undiscussed Horrific Abuse, One Victim of Many]

I'm having trouble discerning if that is the issue. I am including the
full block of code with the preceding portion that generates key_urls:

        for key, props in manifest['paths'].items():
            txid = props['id']
            file_txids[key] = txid
            self._debug(f'{key}: {self.gateway}/{txid}')
            if self.combining.get(key, False):
                for url in (*self.txid_urls(txid), *self.txid_uris(txid)):
                    key_urls.append((key, url))
        if self.closed:
            key_urls = '\n'.join((' '.join(keyurl) for keyurl in
key_urls))
            result = subprocess.run(
                ('git', 'annex', 'registerurl', '--batch'),
                input=keyurls,
                stdout=subprocess.PIPE,
                stderr=subprocess.PIPE,
                check=True,
                text=True
            )
            for line in result.stdout:
                self._debug(line)
            for line in result.stderr:
                self._info(line)
