Issue in Module 2 graded assignment

I am unable to complete the Module 2 graded assessment in the Retrieval Augmented Generation (RAG) course because the grader reports that “BM25_RETRIEVER” is not defined. However, this variable is already provided as a pre-defined global variable in the assignment.

Additionally, all test cases pass successfully in the lab environment, but I still receive a total score of 0 in the graded assessment.

For reference, I have attached screenshots showing the error message and the successful test case results. Can anyone help me to solve this?

Based on similar posts from the past, in this case, it may be worth resetting the assignment to its original format. It could be that the assignment name or something else has been changed, which may be causing the issue.

Before you reset it, though, make sure to save your current file under a different name or keep a copy of everything you have already completed, so you can reuse your work afterward.

Give this a try and let us know if the issue persists.

Thanks. I done this and now the issue is cleared.
