whats wrong with this sentence?

One of the lifelong memories many of us share are the moment we obtained a driver’s license.

The subject is "one." Does the verb agree with it?

One memory ARE? One memory is plural, more than ONE?

The sentence "One of the lifelong memories many of us share are the moment we obtained a driver’s license" has a subject-verb agreement error. The subject of the sentence is "One of the lifelong memories," which is singular. However, the verb "are" is plural. The correct verb form should be singular to agree with the subject. The correct sentence should be: "One of the lifelong memories many of us share is the moment we obtained a driver’s license."
