Describe the bug Running Langflow v1.0.0a24 version locally on macOS Sonoma 14.4.1 and hitting the below error.

ValueError: Error building vertex Astra DB Search: {"errors":[{"message":"Unknown namespace default_keyspace, you must create it                                                        
                             first.","errorCode":"NAMESPACE_DOES_NOT_EXIST"}]}

See the attached file for detailed console error. Follwed the following resources,

• https://pre-release.langflow.org/guides/rag-with-astradb

langflow-rag-with-astra-a24-error-20240423.txt

Browser and Version

• Browser [safari]
• Version [Version 17.3 (19617.2.4.11.8)]

To Reproduce Steps to reproduce the behavior:

1. Start following https://pre-release.langflow.org/guides/rag-with-astradb and then you hit this error at the below step,

3. Validated Astra DB console and can ensure that `default_keyspace` namespace is also available. The token is of type `Organization Administrator` permission (https://docs.datastax.com/en/astra/astra-db-vector/administration/manage-database-access.html#organization-administrator-role) too.

Screenshots added all applicable details above.

Additional context I'm only using the default Open AI embedding and unsure I'm receiving an error related to Google Vertex AI here. Thank you in advance!

Hey @msmygit

Thank you!

Looking into it now.

[ogabrielluiz]

Could you try setting the namespace in the Advanced parameters of the component?

[msmygit]

Thank you @ogabrielluiz . FWIW, I also have ASTRA_DB_NAMESPACE=default_keyspace on the env file which didn't make a difference, but let me try the advanced section route.

[msmygit]

No luck,

[ogabrielluiz]

Could it be that you are using the wrong credentials?

I just tested it here and it is working.

[msmygit]

I tried with the Organization Administrator role and still the same result. Is there a place where I need to provide the secure connect bundle?

FWIW, in order to validate the token permissions, I also tried using it via a standalone CQLSH and it works fine and I can see the presence of default_keyspace:

cqlsh-astra-vector % /Users/username/Downloads/cqlsh-astra-vector/bin/cqlsh -u token --disable-history -p 'AstraCS:MASKED' -b /Users/username/Downloads/secure-connect-vector-ec62fc37.zip

Also, attempted to upgrade to langflow-1.0.0a28 with the same result. Is there any other triage info that I could give you to narrow down this issue?

[msmygit]

fwiw, logs/langflow.log is empty too.

Hello @msmygit, Sorry for the delay. Did you try using the new version? Does the error still persist?
