# Filestack OCR tasks need a signed policy, and re-run per request

## TL;DR

For Filestack OCR tasks, sign a policy with read and convert scopes or you get a 403 naming the task. And do not call the OCR URL on every page view: it re-runs each time, so extract once at upload time and store the result yourself. Context: Official Filestack blog (filestack-processing-tasks): documents two real gotchas.

Use this when you run into the situation in the title.

**When not to use this skill:** unrelated tasks. It covers only the procedure above.

## Compatibility

The steps above apply to the commands named in them. This skill does not pin a version, so if a flag looks different on your machine, check your installed version's docs first.

## Details

First, the OCR and document detection tasks require a signed policy once app security is on. A missing signature returns HTTP 403 naming the task, e.g. 'security required for tasks: ocr', and the policy needs the read and convert calls. Second, the OCR tasks answer Cache-Control: private and run again on every request, so a page that renders extracted text should store the JSON in its own database instead of hitting the transformation URL per view.
