Unsupported deviceFrame: {config['deviceFrame']}

Error message

Unsupported deviceFrame: {config['deviceFrame']}

What it means

Raised by validate_config when config['deviceFrame'] is not in ALLOWED_DEVICE_FRAMES = {"none","iphone-dynamic-island"}. Default is 'iphone-dynamic-island'. Note the cross-field constraint: container='none' combined with deviceFrame='iphone-dynamic-island' is rejected separately (error 576).

Solutions

1. Set deviceFrame to one of: none, iphone-dynamic-island.
2. If container is 'none', you MUST use deviceFrame 'none' (iphone-dynamic-island requires an app container — see error 576).
3. For an unsupported device frame, request it upstream or render without a frame (deviceFrame=none).
4. Pre-validate: `assert c['deviceFrame'] in {'none','iphone-dynamic-island'}`.

Example fix

// before
{"deviceFrame": "pixel"}
# -> ValueError: Unsupported deviceFrame: pixel

// after
{"deviceFrame": "iphone-dynamic-island", "container": "wechat"}

When it happens

Trigger: User sets `"deviceFrame": "pixel"`, `"deviceFrame": "iphone-notch"`, `"deviceFrame": "android"`, or any frame name not in the allowed set.

Common situations: Wanting an Android frame not yet supported; guessing iPhone variant names ('notch', 'xs'); typo; legacy config; combining 'none' container with a frame that the script does not whitelist.
