Deleting and recreating a dataset prevents kernel push (error 500)

I have 2 private data sets that are identical except for the title and id: myuserid/dataset1 and myuserid/dataset2.

The following commands give exactly the same results for the two datasets:

`kaggle datasets files myuserid/dataset1`
`kaggle datasets files myuserid/dataset2`

`kaggle datasets status myuserid/dataset1`
`kaggle datasets status myuserid/dataset2`

`kaggle datasets download myuserid/dataset1`
`kaggle datasets download myuserid/dataset2`

Yet, pushing a kernel with `"dataset_sources": ["myuserid/dataset1"]` works consistently, whereas pushing with `"dataset_sources": ["myuserid/dataset2"]` always results in this error:

`500 - An internal server error occurred. Please ensure that your API client is up to date. If it is, please report a bug at github.com/Kaggle/kaggle-api`

I tried deleting and recreating myuserid/dataset2 with different files, but the error persists. I also tried making myuserid/dataset2 public, but still the same error. Also tried to reinstall kaggle, but still no.

It almost seems as if the id "myuserid/dataset2" was somehow 'blacklisted' on the server. Is this even possible?
