install plugin which creates sql-table

Expected result

Install should works succesfully as it installs successfully with joomla 3.10.1

Actual result

get istaller error

Warning

defined sql-install:

        <install>
		<sql>
			<file driver="mysqli" charset="utf8">sql/jphp.install.sql</file>

Additional comments

Install process finishes succsessfull if "driver" is ommitted - but then sql-tabel is not installed.
