How to serializer an ImageField from another model in django rest framework

I know there are many similar questions but none of them solves my problem.

I have a simple topic that has an image field, a topic title, a topic content, a topic slug and etc.

That topic is associated with a user using the foreignkey. The serializer is doing fine until the

serializer for the image field was added.

serializers.py

class TopicDetailSerializer(serializers.ModelSerializer):
    topic_author = serializers.SerializerMethodField('get_topic_author')
    topic_author_picture = serializers.SerializerMethodField(
        'get_topic_author_picture')

    class Meta:
        model = Topic
        fields = ['id', 'topic_title', 'topic_content', 'created_date',
                  'topic_slug', 'thread_title', 'topic_author', 'topic_author_picture', ]

    def get_topic_author_picture(self, topic):
        return topic.owner.profile_picture

    def get_topic_author(self, topic):
        return topic.owner.username

The output in the console when I request the data from frontend:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0x89 in position 0: invalid start byte

Ain't I just storing the path to the Image rather than the image itself? I mean I have a user profile serializer which sends information to the requested user and it includes an image. But it works fine.

use FieldFile.url as

def get_topic_author_picture(self, topic):
    return topic.owner.profile_picture.url
