fastboot flashall fails ('Unsupported reboot option reboot-fastboot') - AOSP 10.0.0 - blueline

I've just built android 10.0.0_r14 for a Pixel 3 (blueline) from a freshly downloaded AOSP repo under Ubuntu.

The init / sync / make sequence seems fine, but when I attempt to flash the resulting images, fastboot fails:

/home/XXXX/src/aosp$ /home/XXXX/Android/Sdk/platform-tools/fastboot flashall
--------------------------------------------
Bootloader Version...: b1c1-0.1-5578427

Rebooting into fastboot                            FAILED (remote: 'Unsupported reboot option reboot-fastboot')
fastboot: error: Command failed

This appears to occur for any version of 10.0.0, and whether I use fastboot from the Android SDK or the version I compile from AOSP.

Has anyone else seen this? If so, have you overcome it?

I faced the same issue and got resolved by Flashing factory image. Once the device is up re-flash the built image. this works fine for me.

I also faced the same issue when I was flashing the pixel 3. Here is my solution: First I flashed the Android 10 Factory Images Of Pixel 3 from Google. I used 10.0.0 (QQ1A.200105.003, Jan 2020, TMO/Fi). Then I tried to flash with my built aosp again. And this time it works perfectly.
