RangeError: Invalid string length

[boksandaniel]

Since upgrading the RN from 0.75.4 to 0.77.0 I'm encountering snapshots fails when I run these kind of tests.

it('ExampleTest - default', () => { const tree = render( <ThemeProvider> <ExampleTest /> </ThemeProvider> ).toJSON();

expect(tree).toMatchSnapshot();

});

  44 |     ).toJSON();
  45 |
> 46 |     expect(tree).toMatchSnapshot();
     |                  ^
  47 |   });

Facing the same problem. Did you get it working?

In my case, it seems to be related to react-native-reanimated version 3.16.0

It seems it was created by excluding the mock files needed in Jest: https://github.com/facebook/react-native/pull/51530

I have no work-around yet.
