50% failed precondition rate when viewing metrics on storage bucket

[theluk]

Hello,

I see a metric in my bucket observability that says that Client Error Rate is sometimes up to 50%.

 Looking at the details, I can see that a lot of them is FAILED_PRECONDITION.

I was googling for this error but could not find anything related to cloud storage or how to solve this. I also don't understand how to further investigate this or if this is even a real problem.
