https://github.com/basepair/webapp/blob/c1ad441ec736e001f77b81b497001532c5b9fc16/www/bango/settings.py#L45 in settings.py of webapp expects the secrets as json which should look like:

{
  "api": {
     ...
  },
  ...
}

not like:

{"SecretString": '{"\n "api": ...}'}

This can also be seen in the case of aws_sm

Line 52 in 455534a

secret = response.get('SecretString')
