Did I mess up?

I had my cats at my partner’s place for a few days because of a winter storm in my area, and I was worried about losing power in my area. He lives with a roommate who has a Shiba, and we knew to keep her away from the cats because of their high prey drive. She actually got into his room once and chased the cats and it was really scary and stressful. They remained in the bedroom the entire time.

When I had to leave and head back home, I had packed all of my bags in the bedroom and needed to keep the bedroom door open to move everything quickly. I was alone in the house and decided to put the Shiba in the spare bathroom for like 3 minutes max. She freaked out and started frantically scratching the door. I immediately opened it after a few minutes, and I heard from his roommate that she scratched up the paint on the door. I apologized and offered to fix up the paint on the door. He didn’t respond to my apology. Is it harmful to keep a dog in the bathroom like that for a few minutes ? I’ve only had cats in the past.
