I am getting this error regarding key. I am not able to use the key which i got from core service as mentioned here https://github.com/capitalone/Hygieia/tree/master/UI#encryption-for-private-repos
I got the key, I have copied into api.properties as well as bitbucket.properties (I am trying to use this with bitbucket) due to this, I am not able to authenticate bitbucket URL and it’s giving me unauthorized as

2017-06-08 20:34:00,086 ERROR c.c.d.c.DefaultBitbucketCloudClient - 401 Unauthorized:https://bitbucket.org/api/2.0/repositories/awsagero/testapi/commits?sha=master&since=2017-06-08T20:22Z2

before adding this key in api.properties i was not getting any error. But now i am getting this error even if i remove key form api.properties, can someone please help me with this issue.

Thank you
