struct.error: unpack requires a buffer of 4 bytes

This error is typically encountered when attempting to unpack a binary data stream that is smaller than expected. The unpack function in Python is used to extract data from a packed binary string, which consists of a series of bytes that have been encoded in a specific format.
In this case, the error message indicates that the unpack function was expecting a buffer of at least 4 bytes, but the actual buffer size was smaller. This could be due to a few different reasons, such as:
- The binary data stream was truncated or corrupted, causing it to be smaller than expected.
- The format string used to unpack the data specifies more fields than are actually present in the binary data stream.
- The code attempting to unpack the binary data is using the wrong format string, causing it to interpret the data incorrectly.
To resolve this error, you should first check that the binary data stream being unpacked is complete and not corrupted. You can also try modifying the format string used to unpack the data, or double-check that it matches the expected format of the binary data.
