TRACE 1667.000 No serial data received.

I'm trying to install my own firmware onto an NodeMCU (ESP8266) board without any success. I tried using Brave and Edge with the same result. I'm trying to follow the instruction from https://esphome.github.io/esp-web-tools/.

Here's my html file:

install-fw.zip

And here's my manifest:

{ "name": "Firmware", "version": "2.0.0-rc.19", "new_install_prompt_erase": false, "builds": [ { "chipFamily": "ESP8266", "parts": [ { "path": "firmware.ino.bin", "offset": 0 } ] } ] }

After I click on Connect, select to serial port and click Connect again, I get the dialog with two options: 1) Install Firmware and 2) Logs & Console. And on the web page console the following:

ESP Web Tools 10.1.0 by Open Home Foundation; https://esphome.github.io/esp-web-tools/ install-dialog-CQzvAv3p.js?module:491 Initializing Improv Serial install-dialog-CQzvAv3p.js?module:823 Improv initialization failed. Error: Improv Wi-Fi Serial not detected at install-dialog-CQzvAv3p.js?module:491:1210 _initialize @ install-dialog-CQzvAv3p.js?module:823 await in _initialize firstUpdated @ install-dialog-CQzvAv3p.js?module:823 _$AE @ styles-B7oMzmOl.js?module:1 performUpdate @ styles-B7oMzmOl.js?module:1 scheduleUpdate @ styles-B7oMzmOl.js?module:1 _$ET @ styles-B7oMzmOl.js?module:1 await in _$ET requestUpdate @ styles-B7oMzmOl.js?module:1 _$Ev @ styles-B7oMzmOl.js?module:1 A @ styles-B7oMzmOl.js?module:1 dt @ styles-B7oMzmOl.js?module:1 ja @ install-dialog-CQzvAv3p.js?module:491 e @ install-button.js?module:1 await in e (anonymous) @ install-button.js?module:1

I then click on Install Firmware and I get the Confirm Installation dialog. I click on Install and I get the Installing dialog with a spinning cursor. In the page console I get a whole bunch of the following:

TRACE 1667.000 No serial data received. install-dialog-CQzvAv3p.js?module:491 Error reading from serial port: FramingError: Framing error readLoop @ install-dialog-CQzvAv3p.js?module:491 await in readLoop newRead @ install-dialog-CQzvAv3p.js?module:491 read @ install-dialog-CQzvAv3p.js?module:491 readPacket @ install-dialog-CQzvAv3p.js?module:491 command @ install-dialog-CQzvAv3p.js?module:491 await in command sync @ install-dialog-CQzvAv3p.js?module:491 _connectAttempt @ install-dialog-CQzvAv3p.js?module:491 await in _connectAttempt connect @ install-dialog-CQzvAv3p.js?module:491 await in connect detectChip @ install-dialog-CQzvAv3p.js?module:491 main @ install-dialog-CQzvAv3p.js?module:491 (anonymous) @ install-dialog-CQzvAv3p.js?module:823 _confirmInstall @ install-dialog-CQzvAv3p.js?module:823 await in _confirmInstall handleEvent @ styles-B7oMzmOl.js?module:1 install-dialog-CQzvAv3p.js?module:491 TRACE 1667.000 No serial data received.

Clicking Connect on https://esphome.github.io/esp-web-tools/ produces similar error messages. However, I can install WLED from https://install.wled.me/ without any problems (I learned about the ESP Web Tools from that page).

Any help would be appreciated, TIA!

Update: I was able to install the firmware on a Mac laptop running macOS 12.7.6 and the Brave browser.
