TypeError: Cannot read property 'send' of undefined

[lmerega]

Hallo, I cloned this repo on my arm64 Debian server. The problem is that now I have this error: TypeError: Cannot read property 'send' of undefined at /root/voicy/dist/helpers/urlToText.js:57:16 at new Promise () at urlToText (/root/voicy/dist/helpers/urlToText.js:47:12) at /root/voicy/dist/handlers/handleAudio.js:74:83 at Generator.next () at fulfilled (/root/voicy/dist/handlers/handleAudio.js:5:58) at processTicksAndRejections (internal/process/task_queues.js:97:5) {

Any idea?

Thanks

Luca
