I have a problem with gunbot installed on a raspberry pi, using the tradingview plugin. When the bot receive the tradingview alert i get this error message:
emailParsed { timestamp: 1571255520345,
  type: 'short',
  exchange: 'bitmextestnet',
  pair: 'XBT-USD',
  tl: undefined }
TypeError: Cannot read property 'needLock' of undefined
    at status (/snapshot/Gunbotv12.8.3Starter/bot.gunbot.js:0:0)
    at Timeout.setInterval [as _onTimeout] (/snapshot/Gunbotv12.8.3Starter/bot.gunbot.js:0:0)
    at ontimeout (timers.js:478:11)
    at tryOnTimeout (timers.js:302:5)
    at Timer.listOnTimeout (timers.js:262:5) 'Uncaught Exception thrown'
I have no problem running the bot on my PC with the same settings and alerts. Can anyone help me with fix the problem?
