The IAM user or role making the call has no permission for that action on that resource — the message names both.

S3 bucket names are global across all AWS accounts, and someone else already uses this one.
Stack is in ROLLBACK_COMPLETE state and can not be updated
The stack’s first creation failed and rolled back; a stack in ROLLBACK_COMPLETE can only be deleted, not updated.

Storage account names are globally unique across Azure; another customer (or you elsewhere) already uses the name.

npm ERR! `npm ci` can only install packages when your package.json and package-lock.json are in sync
package-lock.json doesn’t match package.json, so npm ci refuses to install.
TypeError: x is not a function
You called something as a function, but its value is not a function (it’s undefined, a string, an object…).
AttributeError: 'X' object has no attribute 'y'
You accessed an attribute or method that doesn’t exist on that object type.
java.lang.ClassCastException: class A cannot be cast to class B
An object was cast to a type it isn’t.

AWS S3: AccessDenied (403) when calling GetObject / PutObject
An IAM policy, bucket policy, ACL/ownership setting, Block Public Access or KMS key policy denied the S3 request.
Azure: AuthorizationFailed — The client does not have authorization to perform action
The signed-in identity (user, service principal or managed identity) lacks an Azure RBAC role for that action on that scope.
PERMISSION_DENIED: The caller does not have permission (insufficient permissions)
You are authenticated, but your identity isn’t allowed to perform this action on this resource.
AWS S3: NoSuchKey / NoSuchBucket — The specified key/bucket does not exist
S3 found no object at that key (or no bucket with that name in the region/account you’re calling).
S3 PermanentRedirect: The bucket you are attempting to access must be addressed using the specified endpoint
The request went to the wrong S3 region/endpoint for that bucket.
AccessControlListNotSupported: The bucket does not allow ACLs
The upload sets an ACL (like public-read), but the bucket uses “Bucket owner enforced” Object Ownership, which disables ACLs.
