Issue

Closes #2975

Change

Because the HuggingFace pipeline/feature-extraction API was changed, the test or the embed call failed. See the post at https://huggingface.co/sentence-transformers/all-MiniLM-L6-v2/discussions/115#6824b067f13f465f51eb1ea9

The PR is ready for review.

The fix is very simple. Don't know why some checks failed.
