Description

The unit test Speculative Answer Generation Chain › Simple RAG › should refuse to answer if information is not in context in the file src/modules/agent/chains/speculative-answer-generation.chain.test.ts fails because the language model (I'm using OpenAI) used in the implementation is ignoring the instruction to not answer the question if the answer is not provided in the context during the unit test execution.

Steps to Reproduce

Run the unit tests using npm run test speculative-answer-generation.chain.test.ts
Observe that the test Speculative Answer Generation Chain › Simple RAG › should refuse to answer if information is not in context fails.

Expected Behavior

The test should pass by confirming that the language model refuses to answer questions when the required information is not present in the provided context.

Actual Behavior

The language model attempts to answer the question even when the necessary information is not included in the context, leading to the test failure.

Additional remark

I have just passed the Answer Generation Chain step in your GraphAcademy course. Filing this issue assuming there is no future step in the course, that will make the test pass later on.

initGraph is unable to instantiate the Neo4JGraph when running the test graph.test.ts. The failure message returned from the test is:

Could not use APOC procedures. Please ensure the APOC plugin is installed in Neo4j and that 'apoc.meta.data()' is allowed in Neo4j configuration

I'm using Neo4J 5.18.1, and my APOC plugin is installed.
I've tested this on a local database, and my sandbox, and it returns the same error above.

I am an employee of infocz, neo4j's Korean partner company.
I am writing a comment because an error occurred while learning the "chatbot with typescript" course.

if i run this code "npm run test cypher-evaluation.chain.test.ts"
Line 61 "expect(found).toBe(true);" An error occurs in the code

The reason is that the error was not found through "error.includes("label Muvee does not exist"))" and the "found" variable could not be changed to "true".

So I checked the chain response error message through "console.log(errors)", changed it to "error.includes("Label 'Muvee' does not exist")", and the test was successful.

If you are experiencing the same problem, I hope this helps.
