Unhandled Error Error: Writing to COM port (GetOverlappedResult): Operation aborted

[olimexsmart]

``Hi,
I struggling to get rid of the error in the title. I'm developing an Electron app on Windows.
From my understanding this error happens when a port is closed when data is still being sent.

This is the code I have now that closes the serial port, which is part of a class that wraps all the interactions with the serial port:

    deInitialize() {
        this.pauseRequests()
        // Close port
        return new Promise((resolve) => {
            if (this.#port.isOpen) {
                this.#port.drain(() => { // Wait for write buffer to empty out
                    this.#port.close(() => {
                        resolve()
                    })
                })
            } else {
                resolve()
            }
        })
    }

What am I doing wrong? Any suggestion on how the port should be closed?
