TL;DR

The issue is likely caused by an invalid count value in the String.repeat function, which can be fixed by updating the code to handle negative count values.

Guidance

  • The error message indicates a RangeError: Invalid count value: -1 at String.repeat, suggesting that the code is attempting to repeat a string with a negative count.
  • To fix this, the code should be updated to handle negative count values, potentially by adding a check to ensure the count is a non-negative integer.
  • The issue is occurring in the renderBorder function at line 37307 of the chunk-AQRXALHQ.js file, which may need to be modified to handle this case.
  • To verify the fix, run the application again and check for the presence of the error message.

Example

// Before
const repeatedString = someString.repeat(count);

// After
const repeatedString = count >= 0 ? someString.repeat(count) : '';

Notes

The provided information does not include the exact code changes required to fix the issue, so the above example is a general suggestion.

Recommendation

Apply workaround: The code should be updated to handle negative count values to prevent the RangeError.
