Hi Garret,
Sorry you are facing these issues. The Gdal error is new. Not seen that. However if it an access issue from s3.. check this thread. Maybe it will help.
Regarding creating of the service.. Here is what I did.
1. Create a new OIC.
2. Add data using Folder. (selected Terrestrial 360 Camera)
3. Open the attribute table.
4. Delete the fields HFOV and VFOV. This way the program will read the values from the default parameters.
5. Clicked on a point on the map using the OIC tool.
This was my result.

If you notice the coverage area (pink triangle) does not match the direction of the image in the viewer. This is because your heading values are -999. One quick way of sorting that out is to use the Calculate Heading tool.

After running the tool you should see this in your attribute table.

Notice CamHeading field.
But then here is where it gave me the Unknown error. but If i revert the headings back to -999 it seems to work. I have a reproducible case with your data now. With your permission I'll pass it on to the devlopers to debug what is happening.
