response?.msg || `Failed to ${action} view state`

Error message

response?.msg || `Failed to ${action} view state`

What it means

checkResponse in the view-state service: the kernel /api/storage/get or patchViewState call answered with a non-zero code, so the transport failed. The thrown message is the kernel response msg, or the fallback 'Failed to get/patch view state' when no msg was provided.

Solutions

1. Check kernel logs for the storage API failure
2. Verify the view-state key exists and is within size limits
3. Retry after confirming the kernel and workspace are healthy
