TypeError: catching classes that do not inherit from BaseException is not allowed

Checked other resources

• I added a very descriptive title to this issue.
• I searched the LangChain documentation with the integrated search.
• I used the GitHub search to find a similar question and didn't find it.
• I am sure that this is a bug in LangChain rather than my code.
• The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

from langchain_community.graphs import Neo4jGraph
url = "neo4j+s://..."
username ="neo4j"
password = ""
graph = Neo4jGraph(
    url=url,
    username=username,
    password=password
)

Error Message and Stack Trace (if applicable)

Description

I am trying to connect to my neo4j aura database but can't seem to get it to work. Any help will be appreciated

I am experiencing the same issue. I am running a simple vector retriever with langchain.
In the jupyter notebook it runs fine. When I execute with a script, it's throwing this error.
