🐞 Description of the bug

the following error message is being displayed for some commands such as solver.setup.materials.fluid["water"] = { "density": { "option": "constant", "value": 1000, }, "viscosity": { "option": "constant", "value": 0.001, }, }
taken from the example https://fluent.docs.pyansys.com/version/stable/examples/00-fluent/modeling_cavitation.html
