Hey @gxin0426! How can I assist you today? I'm here to help you with bug fixes, answer questions, and guide you on contributing.

To resolve the "INVALID_PROMPT_INPUT" error in LangChain when executing the smart_scraper_graph, ensure that all required variables are provided to the PromptTemplate. Specifically, the error indicates that the 'content' variable is missing. You should verify that the PromptTemplate is correctly receiving both the 'content' and 'question' variables.

Here are some steps you can take:

1. Check the PromptTemplate: Ensure that the PromptTemplate is correctly defined and that both 'content' and 'question' are included in the inputs.

2. Provide All Required Variables: Make sure that when you are executing the graph, both 'content' and 'question' are being passed to the PromptTemplate.

3. Escape Curly Braces: If 'content' is intended to be a part of the string and not a variable, escape it with double curly braces like {{"content"}}.

4. Inspect Inputs: Use logging or debugging tools to inspect the inputs being passed to the PromptTemplate to ensure they are correct.

If the error persists, consider downgrading the scrapegraphai library to version 1.37.0, as this has been a solution for similar issues in the past:

pip install scrapegraphai==1.37.0

This approach should help you resolve the error and ensure that the PromptTemplate receives all necessary inputs ^[1].

After creating a virtual environment and running in version 1.37.0, following error pops up:

File "...Scrapegraph-ai/camilo/lib/python3.11/site-packages/httpx/_transports/default.py", line 118, in map_httpcore_exceptions
    raise mapped_exc(message) from exc

Please update to the new version

Hi, @gxin0426. I'm Dosu, and I'm helping the Scrapegraph-ai team manage their backlog. I'm marking this issue as stale.

Issue Summary:

• You reported an error with the GenerateAnswer Node due to a missing 'content' variable in the PromptTemplate.
• I suggested ensuring all required variables are provided and recommended downgrading to version 1.37.0.
• After downgrading, cecabrera encountered a connection error.
• VinciGit00 suggested updating to a newer version as a potential solution.

Next Steps:

• Please confirm if this issue is still relevant with the latest version of the Scrapegraph-ai repository by commenting here.
• If there is no further activity, this issue will be automatically closed in 7 days.

Thank you for your understanding and contribution!
