Problems running PageBuilder Engine in my local environment following a PageBuilder release

Symptoms

  • Unable to run local environment for development immediately following the latest PageBuilder Engine release

  • Running npx fusion start produces a variety of errors in the console

  • FUSION_RELEASE variable is not set locally or is set to latest

Cause

If you do not set FUSION_RELEASE or is set to latest , the latest release will be used which may not be compatible with your environment. For example, if your code has not been upgraded to be compatible with 4.0  , you would want to set FUSION_RELEASE=3.X.X. 

Solution

  1. Set the local environment variable to this: FUSION_RELEASE=<the dev engine version you usually deploy with> in .env.

  2. Run npx fusion start again.
