Browse files Browse the repository at this point in the history
* feat(log): Adding Support for JSON logging

* Passing in log_type to other lambdas

* Casting e as Error

* Add log_level variable, fix formatting

* Correcting failed resolution

* Using latest releases for testing

* Passing in log_level to sub-modules

* Update terraform.yml

* Manually removing `node-fetch`

* Moving logger object to new file

* Resolving merge from develop
Wouldn't be a conflict resolve without a miss

* Logging when job is not queued

* Updating handler names
