7 week old still not sleeping in bassinet - help

Our daughter will ONLY sleep on one of us. The second we try to transfer her to the bassinet she wakes up. I've tried everything - warming it first, waiting longer before transferring, all of it. Meanwhile my wife is getting zero actual sleep and I'm starting to think I caused this by letting her sleep on me too much in the first weeks.

We were in Denver visiting my parents and staying in an Airbnb and she slept in the bassinet just fine there?? So it's not the bassinet itself. Is this just something we have to wait out or am I missing something obvious? She's our first so I genuinely don't know if this is normal or if we've created a problem.
