Unable to get the name of the input when using getByRole while testing with testing-library

I'm testing a component (let's call it MyComponent) which contains a Material Ui TextField component:

<TextField
              name="code"
              aria-label="code"
              onKeyPress={keyPressHandler(codeRegExp)}
              value={values.code}
              placeholder={codePlaceholder}
              onChange={handleChange}
              InputProps={{
                classes: {
                  input: classes.code,
                },
              }}
              onBlur={handleBlur}
              helperText={
                touchedValues.code && errorValues.code ? errorValues.code : ''
              }
              FormHelperTextProps={{classes: {root: classes.errorMessage}}}
            />

I wrote the test for that:

test('Checking the initial rendering of the component', () => {
    const initialState = {
      refs: {
        choice: '',
        creationDate: '',
      },
    };
    render(<MyComponent />, {initialState});
    expect(screen.getByRole('textbox', {name: /code/i})).toBeInTheDocument();
  });

The test fails and I got this error:

 TestingLibraryElementError: Unable to find an accessible element with the role "textbox" and name `/code/i`

    Here are the accessible roles:

      textbox:

      Name "":
      <input
        aria-invalid="false"
        class="MuiInputBase-input MuiInput-input makeStyles-code-9"
        name="code"
        placeholder="ABC_123"
        type="text"
        value=""
      />

Should I add the role=textbox for the TextField Component or does the textbox role does not works with input elements?
