Angular - Http with API returning number larger than 16 digits

Question

As you can see in the question, I try to fetch an API I made with Python that return ID as a number (very important !). But the tool I use is generating ID as number and with more than 16 digits.

So when I fetch my API, all ID is wrong because it exceeds 16 digits.

I have already tried to cast in BigInt for example. But it doesn't work because the cast seems to be applied just after the HTTP result (in chrome's network section I can see the right ID)

Have you any idea of how to deal with more than 16 digits? Or I should consider moving to another tool?

I'm using PysonDB in python to store in json my data.

Thank you for any answer :)
