Flow Emulator Broken since version 2.0.5 #1781

Open damian-psiware opened 1 day ago

damian-psiware commented 1 day ago

Instructions

Update the flow emulator to version 2.0.5. Also for version 2.0.6. Then I go to my current Cadence project and run "flow emulator" and throws the error described below.

If I create a new flow project with "flow init" it works fine.

Problem

The emulator brokes, this is the error message:

❯ flow emulator

Hey @damian-psiware , this may be related to references to previewnet remaining in your flow.json file - can you confirm that previewnet is not anywhere in this file?
