Dog keeps waking me up in middle of the night-Help

I have a 6year old blue heeler/shiba inu mix. She is great at home by herself. She doesn't need to be crated and doesn't have any accidents unless she gets sick (which is rare). Me and my partner both work. My schedule is incontinent but she will be by herself crate free anywhere from 2-9 hours without any problems.

However, recently she has started to wake me up in the middle of the night around 1-2am to ask to be let outside to I think pee. The yard has dark parts which she goes to to do her thing. She'll come back in on her own, but I can't keep ruining my sleep.

I've closed my door to see if that will stop her, but she'll just be outside my door barking and whining to get my attention. She only does this to me. If my partner has his door open she won't bug him at all. Once she comes back in she doesn't even want attention.

Its almost like she has the ability to hold her bladder but knows that if I'm here she can wake me up in the middle of the night instead to go outside. I don't know what to do to get her to stop waking me up.
