Node.js "TypeError: process.nextTick is not a function"?


Is hosting a discord.js bot. The bot’s function is using fs.watchFile and fs.readFile to monitoring changes in a text files and send Discord embed that summarises the data entries within a target.txt file. However, the bot always crash after running for a few hours and throwing process.nextTick error:

   process.nextTick(resume, websocket._socket);

TypeError: process.nextTick is not a function
   at Receiver.receiverOnConclude (C:\Users\Administrator\Desktop\Bot\node_modules\ws\lib\websocket.js:1035:11)
   at Receiver.emit (node:events:526:28)
   at Receiver.controlMessage (C:\Users\Administrator\Desktop\Bot\node_modules\ws\lib\receiver.js:576:14)
   at Receiver.getData (C:\Users\Administrator\Desktop\Bot\node_modules\ws\lib\receiver.js:423:42)

   at Receiver._write (C:\Users\Administrator\Desktop\Bot\node_modules\ws\lib\receiver.js:83:10)
   at writeOrBuffer (node:internal/streams/writable:389:12)
   at _write (node:internal/streams/writable:330:10)

   at TLSSocket.socketOnData (C:\Users\Administrator\Desktop\Bot\node_modules\ws\lib\websocket.js:1187:35)

All these code is working except getting the process.nextTick’s TypeError every few hours, unsure which part caused the error…or can the error be bypass by monkey patching?


Did not find a way to fix the discord.js script from getting that process.nextTick error but pm2 npm package can at least prevent script from stopping.
