`memory.getBytes()` Does Not Populate Bytearray

[JamesD4]

I'm experiencing an issue with the memory.getBytes() function when using Ghidrathon with Ghidra's Headless Analyzer. When I use the following code to read bytes from memory:

byte_data = bytearray(8)
memory.getBytes(cstring_ptr_addr, byte_data)

Following the call to memory.getBytes(), byte_data remains empty and is not populated with any bytes.

However, when I read the bytes individually using a loop, it works as expected:

byte_data = bytearray()
for i in range(8):
    try:
        single_byte = memory.getByte(cstring_ptr_addr.add(i))
        byte_data.append(single_byte)
    except Exception as e:
        return None

No exceptions or error messages are thrown when memory.getBytes() is called and the bytearray is not populated.
