Steps to reproduce

When upload a file, I got "500 Internal Server Error: The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application."
It works fine when I use 0.10.0, occured after I upgrade to 0.10.1.

The error you're encountering seems to be related to the created_by_role attribute in the MessageFile class. The error message indicates that a string is being used where an enumeration value is expected. Specifically, the line self.created_by_role = created_by_role.value is causing an AttributeError because created_by_role is being passed as a string instead of an instance of the CreatedByRole enumeration.

To resolve this issue, ensure that when initializing the MessageFile object, the created_by_role parameter is passed as an instance of the CreatedByRole enumeration, not as a plain string. This should align with the expected data type and prevent the error from occurring ^[1].

Additionally, there was a similar issue reported in the past related to file uploads, which suggested checking the file size and quantity limits, adjusting the client_max_body_size in NGINX, and ensuring the latest version of the software is used ^[2]. However, since your issue seems to be more about the code logic, focusing on the created_by_role initialization should be your priority.

@dosu It works fine in 0.10.0, so I think it can't be a nginx config issue.

Since the issue started after upgrading to version 0.10.1, it's likely due to changes in the codebase between these versions. The error suggests that the created_by_role attribute is being handled differently in the new version.

Check the release notes or changelog for version 0.10.1 to identify any changes related to the MessageFile class or the created_by_role attribute. It's possible that the way this attribute is initialized or used has been updated, requiring adjustments in your code or configuration.

If the changelog doesn't provide enough information, reviewing the commit history for changes in the relevant files might help pinpoint the exact modification causing the issue. Adjust your code to align with these changes, ensuring that created_by_role is correctly initialized as an enumeration value if that's the new requirement.

Try to remove your local images and deploy them v0.10.1 again.
