ForAnyValue:ArnNotLikeIfExists

compares a list of ARNs in a request to a list of ARN patterns in your policy. The policy values can include asterisks (*) to match multiple characters and question marks (?) to match a single character within an ARN segement. Wildcards cannot be used to span ARN segment, so the partition, service, region, account, and resource must all be present in your policy value, even if they are all wildcards. The comparison is case sensitive.

To match a request, the context key must exist in the request and at least one ARN in the request must NOT match any of ARN patterns in your policy.

You can use policy variables in the value of this operator.

Warning

ForAnyValue:ArnNotLikeIfExists is actively confusing. Any operator starting with ForAnyValue ignores IfExists — it is not evaluated against the entire array, only against a single value at a time inside the ForAnyValue loop. Use ForAnyValue:ArnNotLike instead so your coworkers don't hate you.
