RangeError: Maximum call stack size exceeded when you add extra parameter behind the =deep

[TMSchipper]

I attempted to introduce a 'createdBy' variable on my blog page to specify the author of each blog article. However, whenever I include an additional parameter after 'deep', I encounter a 'maximum call stack size' error.

Example usage:
router?path=/blog&populate=deep,createdBy

Example usage (this example doesn't cause an error, but the data is no longer retrieved):
router?path=/blog&populate=deep,10,createdBy
