Unexpected Bug with Assistant API | Access messages from threads

I looked through some similar topics on the forum after playing with this myself a bit and was unable to get it working. This is where I’m at right now:

	# Returns all the messages in the thread object.
	def getMessages(self):
		messages = client.beta.threads.messages.list(self.thread.id)
		return messages.data[0].content[0].text.value

The error I’m getting is the following:

Cannot access member "text" for type "MessageContentImageFile"
  Member "text" is unknown

The ‘content’ of a message object can be a text object OR an image file object. It sounds like part of your thread contains an image file and cannot return the ‘text.value’ as it does not exist for an image file.

The only thing in my thread is the message “Hello!”. Do you have any advice on how I could go about fixing this issue?

You could try returning ‘messages.data’ and inspect the list of messages. This should return a JSON object and you can see if your “Hello!” message is in the thread as well as determine if there are any unknown messages or types.
