All the media providers succeeded in my testing accept for this "Free photos" provider. When selecting an image, the request always resulted in a 500 response.

I copied each request as a curl command from Proxyman. When comparing the commands, I noted that the GIF provider included the .gif file ending; contrastingly, the "Free photos" provider lacked a file ending. When I manually added a .jpg file ending, the request succeeded.

Do you experience this? What might causing these 500 responses?

[dcalhoun]

I encountered a crash with Patterns on WPCOM Simple sites. I fixed this in wordpress-mobile/GutenbergKit#223. Waiting for approval of that before we move forward merging this PR.

[dcalhoun]

Approving. We need to address the 500 responses when using the Free photos media provider, but the native block inserter is behind a feature flag anyways.
