SyntaxError: Unexpected token } in JSON at position 212 is one of the least helpful error messages a developer sees. It tells you that the JSON is broken, but not why , and the position is a character offset you have to count to. The good news: almost every JSON error comes from the same short list…
ometimes you get a huge JSON array, a few thousand records in one file, and you need it in smaller pieces. Maybe an API only accepts 500 items at a time, or your editor chokes on the file. The easy way is to paste it into an online tool. But if the data is private, uploading it to a random server…
TL;DR : Since 0.34.4, Ollama applies a format schema on a thinking model as a single grammar: anything until the thinking block closes, then the schema. That grammar also allows the response to end before the closing, and it treats everything up to the closing as thinking. So when a model like…
Changing one retry policy in a Step Functions workflow can mean editing the same block of JSON on every Task that uses it. A workflow is defined in the Amazon States Language (ASL), a JSON document of states that name each other, with the logic in expressions. Writing it by hand means wiring every…
Nested Tableau containers can consume a surprising amount of dashboard-building time. In this experiment, I asked an AI to infer a layout from a screenshot, save layout JSON and use cwtwb to generate a workbook. The output deliberately used text placeholders. I explicitly allowed mocked…
Last Friday, while cross-debugging a payment refactoring branch, I had Cursor open on my left monitor for frontend reviews and Claude Code running in my terminal on the right. To let both AI assistants inspect database schemas and query logs, I hooked up 4 MCP servers to each environment. When you…
I build n8n automations for small salons and clinics. The series so far covered preventing no-shows, refilling cancelled slots, and recovering fees. This build covers what happens after a visit goes well: the follow-up that turns a good visit into a review or a next booking. It is the cheapest…
TL;DR: Put a small validation-and-rendering boundary in front of the email API. Parse JSON once, reject unknown or missing template variables, escape user-controlled values, render the exact template version, and record a token-free evidence event before delivery. For a gaming password reset, that…
When you request structured data from a reasoning model using a JSON mime type, the response often arrives split across several content parts rather than sitting neatly in a single text block. This breaks standard assumptions in ingestion pipelines. Developers usually expect the model to return a…
The gap between a demo agent and a reliable one is usually not model intelligence; it is output discipline. In a demo, the model calls get_weather({"city": "SF"}) and looks magical. In production it calls refund_payment({"payment_id": 7712, "amount": "49.00", "currency": "usd", "reason": "user…
