Getting function arguments in ida

Question

I'm trying to extract the callee arguments in my intel x86 binary using IDA Pro 7.3. I tried the following line:

ida_typeinf.get_arg_addrs(call_address)  # call address points at `call some_func`

For some reason, the call always returns None. Is there any other way to do this?

I have found out that if in the disassembler you give the type to the function that is being called, then the ida python function will work as it should.
