Describe the bug

When i try to create a bento in python, i get the following error:

bentoml.exceptions.BentoMLException: Failed to build BentoService bundle (Lookup for traceback):

To reproduce

import bentoml
tmp_dir = Path("mypath")
s = bentoml.bentos.build_bentofile(bentofile=str(tmp_dir / "bentofile.yaml"), build_ctx=str(tmp_dir / "src"))

Expected behavior

Create a bento

Environment

bentoml version: 1.2.9
Python 3.10.14

[xianml]

Sorry. i did not reproduce that under bentoml===1.2.9.
Please try BentoML cli command first to build the same bento to see if there is any specific error.
Or Could you share more context on this issue?

Hello @xianml!
solved this a while ago, it was a error cuased by dagster and not with bentoml.
I forgot to close this issue, but will do it now!

Thanks anyway :)
