Invalid FunctionCall Arguments Type Declaration

[bh2smith]

Prerequisites

• I'm using the latest version of near-api-js.
• I have tried to start with a fresh project and reproduce the defect with minimal code changes.
• I have read the console error messages carefully (if applicable).

Description

This cast in the constructor is misleading and wrong:

near-api-js/packages/transactions/src/action_creators.ts

Lines 98 to 120 in 480fe81

	function functionCall(
	methodName: string,
	args: Uint8Array | object,
	gas = 0n,
	deposit = 0n,
	stringify = stringifyJsonOrBytes,
	jsContract = false
	): Action {
	if (jsContract) {
	return new Action({
	functionCall: new FunctionCall({ methodName, args: args as Uint8Array, gas, deposit }),
	});
	}
	return new Action({
	functionCall: new FunctionCall({
	methodName,
	args: stringify(args),
	gas,
	deposit,
	}),
	});
	}

The unit tests call this constructor with arguments defined via Buffer.from which is an "object"

The constructor takes object OR Unit8Array and casts to Uint8Array while the actual contents are never Uint8Array.

Reproducible demo

No response

Steps to reproduce

Try and construct an example in the tests that are actually Uint8Array to demonstrate to end users how its expected to look.

Expected behavior

Expect that the Type declaration for these arguments is actually something people use.

Actual behavior

This form is dumb.

Your environment

Self-service

• I'd be willing to fix this bug myself.
