Errors handling

Whenever something goes wrong, TwicPics will issue an HTTP error with a sensible status code and a short explanation in plain text as a body.

TwicPics will error when:

• There is a syntax error in the manipulation expression
• The authentication identifier is invalid
• The URL of the source asset is not well-formed, or its protocol is not supported
• The domain of the source asset is not registered (see the documentation about domain name registration)
• The source asset is unreachable (i.e., the GET request to retrieve it resulted in an HTTP error)
• The source asset is of an unsupported format (only AVIF, GIF, HEIF, JPEG, PNG, and WebP, and most video files are currently supported)
• The source asset, the output asset, or any intermediate asset created while processing the transformations doesn't respect the internal pixel and/or byte size limits of TwicPics (i.e., one of the assets has a dimension of zero or is "too big")
• A transformation ends up cropping outside of the asset (for instance, when attempting to crop 500 pixels out of an asset that is only 200 pixels wide)
