Log error chain to CloudWatch

mlafeldt · mlafeldt · commit cd89e7df2e79 · 2022-02-09T11:26:49.000+01:00
The anyhow crate will only include the error chain with {:?} or {:#}. Without this change, only the last error will be logged to CloudWatch and all underlying causes are lost when using with_context to augment errors. Fixes awslabs#348
