title: "Failed to fetch a list of secrets" on AWS Secrets Manager console?
body: <p>Has anyone noticed some unpredictable failures on AWS Secret Manager when trying to retrieve secret values?  I'm using my own encryption key, and I've found that frequently, I am getting a "Failed to fetch a list of secrets" error on the AWS console after encrypting a secret.  This seems to happen if I change the encryption key after an initial encryption, but it has happened without that as well.  </p>
  
  <p>I also think I've seen a case where the encryption key changed from a custom key to default without any action from me.   </p>
  
  <p>I've also seen an issue where two stacks set up nearly identically have an inconsistency where one can read an encryption key when calling Secrets Manager but one cannot.  It looks like an IAM issue, but I haven't found any difference between the two stacks and their IAM settings.  I only mention this in case it gives some clue to the issue above.</p>
