Arrowtypeerror: expected bytes, got a ‘int’ object

by

An ArrowTypeError occurs when the ‘bytes’ data type is expected, but an ‘int’ object is provided instead. This error commonly occurs when trying to use an integer value where a bytes object is required.

To understand this error, let’s consider an example:

# Example 1
message = 123
encoded_message = message.encode('utf-8')  # Trying to encode an integer value
print(encoded_message)

In the above example, we are trying to encode an integer value ‘123’ using the encode() method. However, the encode() method expects a string value, not an integer. Hence, an ArrowTypeError will be raised.

Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
TypeError: expected bytes-like object, not 'int'

To fix this error, we need to provide a string argument to the encode() method instead of an integer:

# Example 2
message = '123'  # Corrected to a string value
encoded_message = message.encode('utf-8')
print(encoded_message)

In the corrected example, we are providing a string value ‘123’, which can be encoded to bytes without any errors.

So, the ArrowTypeError can be resolved by ensuring that the correct data types are used in the code.
