Steps to reproduce

• Include relevant code snippet or link to code that did not work as expected.
• If applicable, add screenshots to help explain the problem.
• If using the Playground, name the pre-existing notebook that failed and the steps that led to failure.
• Include anything else that might help us debug the issue.

I think it's going to be fixed by #2745 but I'm not completely sure

I think it's going to be fixed by #2745 but I'm not completely sure

looks like that is the root cause, just let me know when it's merged and I'll close the issue
