Mac OS Monterey update fail

I tried to update mac os from Big sur 11.6.1 to Monterey and got the following error several times.

An error occurred while preparing the installation. Try running this application again.

The error continued to come up even in safe mode and after a pram and smc reset.

Next I tried a bootable installer USB and the following error comes up.

Mac os a required firmware update could not be installed. Compatible internal storage is required in order to update.

I have a APPLE SSD SM2048L installed in a MacBookPro11,5 with system firmware version MBP114.0184.B00 and smc version 2.30f2.

The SSD is an original Apple SSD made by Samsung.

What am I missing?

MacBook Pro 15″, macOS 11.6

Do you have an Apple SSD installed? I ask because I had problem with upgrading late 2013 MP to Monterey.

A while ago I replace the internal Apple SSD with an NVMe drive with adapter in my late 2013 MP. I successfully updated to Big Sur with no problem but could not update to Monterey. Could not even install Monterey on a blank external drive. Then I Googled and it appeared that an Apple internal SSD has to be installed in order to update the firmware and OS boot loader. I installed the original Apple SSD which had Mojave and updated successfully to Monterey. I then booted from my Big Sur NVMe SSD and successfully updated to Monterey. I am typing this from that OS now.
