Known Issues and Limitations

Currently

• We only support JavaScript-based code
• Each request has a 60-second (wall time) timeout limit
• Each request is limited to 50ms of CPU time
• Each request is limited to 2MB of memory
• An Edgio Function can make fetch requests only to origins defined in your property configuration file (edgio.config.js).

We're looking forward to feedback from our customers about these limitations and how we can improve the product.
