Always

Description

The app crashes on fresh install because of a problem in the Results.js file.

Stacktrace & log output

Warning: TypeError: Cannot read property 'size' of undefined

Can you reproduce the bug?

Always

Reproduction Steps

Our project was built using:

• react-native: 0.71.2
• realm: 11.9.0
• @realm/react: 0.4.3

And had two schemas with no relation between them.

After upgrading to the latest versions of all the packages, the app crashed on runtime giving the following output:
Warning: TypeError: Cannot read property 'size' of undefined.

The issue has been solved by going to the Results.js file in the dist folder and updating the getter length to this:
get length() { return this.internal ? this.internal.size() : 0; }

Version
