Flows are extremely powerful. With great power comes great responsibility - sometimes flows can cause errors in your projects.

Learn how to find and fix flow errors for optimal project performance.

If there is a flow error, the affected feature will appear neon magenta / bright pink on the map.

Sometimes the flow might break the rendering for some or all of the geometries in your project. You will see an engine status error in the bottom left corner of your Giraffe tab.

Try pausing and re-starting the engine (click the pause button to the left of the error text).

If pause and restart doesn't work, try removing the flow from geometries in the project.

Sometimes, a flow error will completely crash your Giraffe tab. (Usually this happens when you have self-referencing nodes or a bad loop).

Try refreshing the tab. If you are unable to get back in, reach out to support for assistance retrieving the file.

Turn on the Spectacles from the top bar. This displays the state of all nodes in the Flow.

Any nodes with an error will appear in Red. Red nodes mean the entire flow is failing due to the error.

Any nodes with a warning will appear in orange. Orange nodes mean that the flow is still able to complete, but some information may be missing.

If a node has an error or a warning, you may want to use the Reader node to review the status.

Add the Reader node to the Status (S) output of the node with the error/warning to see the message.

Try pausing a specific node to see if it is causing the issue. Right click on the node title -> Disable.

Pause the entire Giraffe engine to stop all geometry generation.

Click the pause button in the top bar of the flow editor.

If processing seems stuck, try clicking recompute. This stops the flow process and restarts it.

If all else fails, try refreshing your browser tab.
