When data contains a BigInt variable, trying to apply normalize on this variable throws an error: TypeError: Cannot convert a BigInt value to a number.

I've created a small notebook to reproduce the issue:

It seems that the error may come from this line, but I'm far from an expert on this domain so I may be mistaken:
