It is possible this extends beyond the optional images mentioned in the issue title, but this is where I'm running into it.
To reproduce:
BadRequestHttpExceptionThe exception is thrown from here
$prop_source_array = $client_model[$sdc_prop_name] ?? NULL;
if ($prop_source_array === NULL) {
// The client didn't send this prop but should. This is an error OR the
// data has been tampered with.
throw HttpException::fromStatusCode(Response::HTTP_BAD_REQUEST);
}
And it looks like image is not present in the $client_model sent to it
as it isn't included in the value ofGeneratedFieldExplicitInputUxComponentSourceBase::clientModelToInput if the field hasn't been edited yet.
Speculation...
At first glance, it seems like clientModelToInput() is running into this because it's looking for an explicitly set 'default_value' when no value is set, and when that doesn't exist (such as the yet-to-be-edited optional image), it fails the try block and isn't added to the resulting array.
More Speculation...
clientModelToInput() to handle empty values differently?Active

I suspect 🐛 Cannot place a code component with an image prop Active fixed this, but it'd be good to confirm. 🤞
This is very related to 🐛 SDCs with optional images without examples cannot be placed Active which points the finger at the same code.
