By default log level is set to warning. This can be customized with a custom LogFactory or by defining the "LogLevel" property in the custom resource resource in your template. For example:
`json`
"MyCustomResource": {
"Type": "AWS::CloudFormation::CustomResource",
"Properties": {
"LogLevel": "debug",
//...
}
}
`typescript
import { camelizeKeys } from 'custom-resource-helper';
//...
console.log(event);
/*
{
...
ResourceProperties: {
...
BucketName: 'testbucket',
---
}
...
}
*/
const {
resourceProperties: { bucketName }
} = camelizeKeys(event);
console.log(bucketName); //prints: testBuckets
