It might be possible that something on your web page or browser is interrupting the communication. The desktop application doesn't store any animation data locally, instead it syncs the data with the web page.

Troubleshooting errors can be difficult, here are some pointers that might help you solve the issue:

Outdated runtime

It's important to know that the runtime runs autonomously, meaning that it doesn't depend on the browser extension nor desktop app. You can safely use it in production (even legacy runtimes).

However, if you want to live edit the animations with the desktop application, you'll need the latest runtime to be included on your web page.

Bug fixes and new features are added frequently. The runtime's business logic might change accordingly. Rule of thumb for live editing animations: always use the latest runtime.

Outdated Chrome extension

It might be possible that your browser extensions are outdated, even though a new version of the Spirit extension is available.

Once the desktop application or the runtime player is updated, this might lead to unexpected behaviour.

Features are added along the way and the data format might change over time.

Head over to Browser Extension > Updates for more information about updates on browser extensions in relation to Spirit.

Extension interference

Other extensions can interfere the communication as well.

Check out Browser Extension > Install for more information.

Runtime errors

And then there's another possibility. You might have run into a runtime error. You can check if your web page has thrown an exception. Open Chrome Devtools (Command+Alt+I) and check it on errors.

Something else

Work in progress!
