Hi there, I am currently doing the short course on LangChain and work through the videos including the Jupyter notebooks. When running cell 74 and the following, I get the following error: --------------------------------------------------------------------------- OutputParserException …

@ghizmodave @JasminH @joyu-ai @invited2 @minatu2d The issue is not Solved @ghizmodave - Yes adding the ``` after json does fix the first and second prompts in the multichain prompts from erroring out but the third and final prompt still errors out.

Doesn’t really matter. All short courses are responding with a “Monthly quota exceeded” I’ve been waiting a couple weeks now; waited until we got into August Same results

I get the problem solved by modify the template to: << OUTPUT (remember to include the json) in first line and in the last line>>“”"
