Hello @juan.manuel, welcome to the community
Prismic no longer gives support to that plugin. We've had similar discussions in the past about this. Take a look at this thread if you're interested in knowing more details:
You can follow the dedicated guide to migrate to the correct plugin. Afterward, you'll be able to integrate previews using the previews plugin.
Feel free to reach out to us if you need help when migrating to the new plugin.
