How Do I Suppress A Specific Error In Jest Tests

I'm trying to suppress a specific error in our Jest tests as we've got plans to resolve it later, but until then we don't want these errors potentially hiding any true errors.

The errors occur across the codebase so my current strategy is to rewire the console.error function in our jest setup file.

I've taken two different attempts, both almost working however now when they report a true error - they're adding a new line onto the error trace.

Attempt 1:

const originalError = console.error.bind(console.error);
jest.spyOn(global.console, 'error').mockImplementation((message) => {
  if (
    !message
      .toString()
      .includes(
        'Warning: An update to SettingsPanel inside a test was not wrapped in act'
      )
  ) {
    originalError(message);
  }
});

Attempt 2:

const { error } = console;
global.console = {
  ...console,
  error: (errorMessage) =>
    !errorMessage
      .toString()
      .includes(
        'Warning: An update to SettingsPanel inside a test was not wrapped in act'
      ) && error(errorMessage),
};

Both of these will log a valid error - i.e. 'Warning: Each child in a list should have a unique "key"' - However instead of pointing me to the code with the issue it points me back here

console.error
    Warning: Each child in a list should have a unique "key" prop.%s%s See https://reactjs.org/docs/lists-and-keys.html#keys for more information.%s

      18 |       .includes(
      19 |         'Warning: An update to SettingsPanel inside a test was not wrapped in act'
    > 20 |       ) && error(errorMessage),
         |            ^
      21 | };

      at Object.error (jest.setup.js:20:12)
      at printWarning (node_modules/react/cjs/react.development.js:315:30)
      at error (node_modules/react/cjs/react.development.js:287:5)
      at validateExplicitKey (node_modules/react/cjs/react.development.js:1630:5)
      at validateChildKeys (node_modules/react/cjs/react.development.js:1656:9)
      at Object.createElementWithValidation [as createElement] (node_modules/react/cjs/react.development.js:1806:7)
      at src/js/components/SettingsPanel/DataListAutocompleter/DataListAutocompleter.tsx:85:13

I've searched and searched and all I can find are questions about silencing all errors or silencing a specific test - nothing I've found has helped me solve this.
