Bonjour Judy,
Without any link to the question or lesson, it is difficult to understand where this query came from.
The closest I can imagine is, "I promise to give you it" but that would be written Je te le promets
where te would be the direct object and le would refer to "it". The verb promettre being conjugated in the first person singular.
Te could be indirect if the meaning was intended to be "I promise to give it to you". In this construction, le would represent a direct object.
Otherwise, this may appear to be some sort of homework query.
Bonne continuation
Jim
