serializers.SlugRelatedField Image Encoding and Decoding Error

[Amed Sheriff]

I am getting and error when using Get or Post.

Code:

identification= serializers.SlugRelatedField(
        queryset=User_ID.objects.all(),
        slug_field='userid'
    )

class Meta:
        model = Transaction
        fields = '__all__'

Error:

encoders.py", line 50, in default
    return obj.decode()
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte

I am trying to use base64 but don't know how to implement it with serializers.SlugRelatedField.

Already figured it out.
