PHP ver 7.3 Codeigniter ver 4.1.2

Problem 1

• Root composer.json requires hermawan/codeigniter4-datatables ^0.5.0 -> satisfiable by hermawan/codeigniter4-datatables[v0.5.0].
• hermawan/codeigniter4-datatables v0.5.0 requires codeigniter4/framework ^4 -> satisfiable by codeigniter4/framework[4.0.0, ..., v4.1.2] from composer repo (https://repo.packagist.org) but codeigniter4/framework[1.0.0+no-version-set] from root package repo has higher repository priority. The packages with higher priority do not match your constraint and are therefore not installable. See https://getcomposer.org/repoprio for details and assistance.

Do you have any suggestion how should composer.json?

It's look fine here. or maybe I'm not sure what you mean...
