'CT_Blip' object has no attribute 'blob'

This error message indicates that the 'CT_Blip' object does not have an attribute named 'blob'. This could be due to a couple of reasons:

1. The attribute 'blob' does not exist in the 'CT_Blip' object.
2. The attribute 'blob' exists in the 'CT_Blip' object but is not accessible due to some access restriction or permission issue.

To resolve this error, you need to check the documentation of the 'CT_Blip' object to see if the 'blob' attribute exists. If it does, then you need to ensure that you have the required access or permissions to access the attribute. If the attribute does not exist, then you need to find an alternative way to achieve the functionality you are trying to implement.
