Use this to report bugs in LangChain. If you're not certain that your issue is due to a bug in LangChain, please use [GitHub Discussions](https://github.com/langchain-ai/langchain/discussions) to ask for help with your issue. Relevant links to check before filing a bug report to see if your issue has already been reported, fixed or if there's another way to solve your problem: [LangChain documentation with the integrated search](https://python.langchain.com/docs/get_started/introduction), [API Reference](https://api.python.langchain.com/en/stable/), [GitHub search](https://github.com/langchain-ai/langchain), [LangChain Github Discussions](https://github.com/langchain-ai/langchain/discussions), [LangChain Github Issues](https://github.com/langchain-ai/langchain/issues?q=is%3Aissue), [LangChain ChatBot](https://chat.langchain.com/) - type: checkboxes id: checks attributes: label: Checked other resources description: Please confirm and check all the following options. options: - label: I added a very descriptive title to this issue. required: true - label: I searched the LangChain documentation with the integrated search. required: true - label: I used the GitHub search to find a similar question and didn't find it. required: true - label: I am sure that this is a bug in LangChain rather than my code. required: true - type: textarea id: reproduction validations: required: true attributes: label: Example Code description: | Please add a self-contained, [minimal, reproducible, example](https://stackoverflow.com/help/minimal-reproducible-example) with your use case. If a maintainer can copy it, run it, and see it right away, there's a much higher chance that you'll be able to get help. **Important!** * Use code tags (e.g., ```python ... ```) to correctly [format your code](https://help.github.com/en/github/writing-on-github/creating-and-highlighting-code-blocks#syntax-highlighting). * INCLUDE the language label (e.g. `python`) after the first three backticks to enable syntax highlighting. (e.g., ```python rather than ```). * Reduce your code to the minimum required to reproduce the issue if possible. This makes it much easier for others to help you. * Avoid screenshots when possible, as they are hard to read and (more importantly) don't allow others to copy-and-paste your code. placeholder: | The following code: ```python from langchain_core.runnables import RunnableLambda def bad_code(inputs) -> int: raise NotImplementedError('For demo purpose') chain = RunnableLambda(bad_code) chain.invoke('Hello!') ``` - type: textarea id: error validations: required: false attributes: label: Error Message and Stack Trace (if applicable) description: | If you are reporting an error, please include the full error message and stack trace. placeholder: | Exception + full stack trace - type: textarea id: description attributes: label: Description description: | What is the problem, question, or error?
