Lesson 4 error: invalid number value. Value must be an integer, hex string, BN or BigNumber instance

Use the same code in github.

When I call the withdraw function, the console shows [this error](error: invalid number value. Value must be an integer, hex string, BN or BigNumber instance).

Well there is no problem in your code. Please reinstall MetaMask on your device. Make sure you have all the keys to your accounts. Please let me now if this work...
