Describe the Issue

Hi,

I'm experiencing an issue when using the Postman plugin to send gRPC requests to my server. When I send a large uint64 value in a request, the value received by the server is different from what I sent. Specifically, when I send 722390671457054703, the server receives 722390671457054720.

It seems that the problem is related to how JavaScript handles large integers. JavaScript uses 64-bit double-precision floating-point numbers, which can't accurately represent very large integers. As a result, large integers are rounded, leading to precision loss.

Thank you!

Steps To Reproduce

Use the Postman plugin in VS Code to send a gRPC request with a large uint64 value (e.g., 722390671457054703). Observe that the value received by the server is different (e.g., 722390671457054720). Expected Behavior: The server should receive the exact uint64 value that was sent in the request.
