If your Azure Databricks tables show up as a knowledge source in Copilot Studio, but the agent cannot access data when you ask questions, the issue is often related to user or service account permissions, network rules, or the configuration of the ta...

Hi @heramb13 , Your chain is being serialized by MLflow; during that process MLflow re-imports each runnable by its module path. The error shows MLflow is trying to import ChatDatabricks from the legacy module path “langchain_databricks”, which isn’t...

Hi @yashshingvi , Thanks for the details—this is a common gotcha with MLflow “models from code.” Why your imports fail code_paths are only added to sys.path when the model is loaded (for inference/serving), not while the driver is executing mlflow.la...

Hi there Sam,I work for Databricks. The pace of innovation with AI/BI is wild (fast). Databricks itself just migrated off a leading BI platform and now exclusively runs its business on AI/BI (Blog). We also have customer testimonials on our website, ...

When using a custom Genie agent with the Databricks Genie REST API (GetMessage endpoint), extracting SQL queries and results works well as a standalone agent. However, integrating this custom agent into a multi-agent framework (especially when combin...

This error is most often due to missing permissions, workspace types, or cluster configuration settings necessary for AI agents and custom tools to access Unity Catalog (UC) functions using Spark Connect in Databricks. The main causes and solutions a...

Greetings @meetiasha , yes—there’s a gap between Databricks’ basic “vector endpoint + catalog index” examples and truly advanced RAG, so below is a step‑wise, LangChain‑first playbook you can run entirely on Databricks notebooks with local vector sto...

You want your RAG solution (based on Databricks Cookbook) to display PDF files at specific pages as references in your Review App, rather than plain text chunks. You also wish to retrieve source documents from your serving endpoint, but your current ...

Yes, it is possible to invoke an Azure AI Search Vector DB endpoint from within a Databricks environment—allowing you to leverage your existing Azure resource for client-specific document retrieval, without needing to create a new vector database in ...

Deploying HuggingFace LLM models to Databricks using MLflow’s llm/v1/chat task sometimes results in unexpected chat behaviors, usually due to prompt/template mismatches, model configuration issues, or pipeline setup requirements. Here’s a direct answ...

Based on your description, you are encountering a 500 Server Error when trying to use the Langchain ChatDatabricks integration with a Databricks Serving Endpoint connected to an external OpenAI GPT-4 Turbo model on Azure. This error usually indicates...
