The cause could not be attributed automatically. The provider's verbatim reason is the best signal for what went wrong. ## Why this happens This is the catch-all code for the CloudFormation family. It covers any resource create, update, or delete failure that does not match a narrower category such as permissions, validation, dependency, quota, or timeout. The specific cause lives in CloudFormation's status reason, which Fjall quotes verbatim in the failure record. ## How to fix it 1. Read the provider reason on the deployment's detail page. It is CloudFormation's own account of the failure and usually names the property, state, or condition at fault. 2. Check the affected-resources list in the failure detail. It shows every resource the failure touched, with the root cause resource first. 3. Fix the named resource. Depending on the reason, that means correcting its configuration in `infrastructure.ts`, repairing its state in AWS, or resolving the condition the reason describes. 4. Run `fjall deploy` again once the cause is addressed. ## What Fjall shows you The failure surfaces on the deployment's detail page on fjall.io, in the CLI's Error Detail block, and in the deployments list row title. The detail page carries the stable code, a per-occurrence detail sentence, the provider's verbatim reason, and the remediation steps, along with the root cause resource and dependency chain from the stack analysis. ## Related The full deploy workflow from build to live.
