This operation is not supported by directory buckets.

Associates an access policy with the specified access point. Each access point can have only one policy, so a request made to this API replaces any existing policy associated with the specified access point.

All Amazon S3 on Outposts REST API requests for this action require an additional parameter of x-amz-outpost-id to be passed with the request. In addition, you must use an S3 on Outposts endpoint hostname prefix instead of s3-control. For an example of the request syntax for Amazon S3 on Outposts that uses the S3 on Outposts endpoint hostname prefix and the x-amz-outpost-id derived by using the access point ARN, see the Examples section.
