Sir, I have successfully imported the model. Next, I want to linearize it using the SystemModelLinearize instruction, but the system prompts this error. How can I resolve it? Thank you!

model = Import["C:\\Users\\james\\Desktop\\Model2.mo", "MO"];
list = model["TopParameterNames"];
vars = list /. {QuantityVariable[x_, __] :> x};
SystemModelLinearize[model, 
  Method -> {"SymbolicDerivative", 
      "SymbolicParameters" -> vars}]

The model position can be changed according to your needs.

Sir, am I writing correctly? But the running results clearly indicate that I wrote incorrectly emm...

model = Import["Model2.mo", "MO"]

And how can I use the ImportString command to load a file? You used it in your previous reply.
