Anyone getting problems following the Getting Started template? Tried 2 different installations and still getting errors.


Some of the errors I am getting:

Error #1: level=warning msg="The \"R\" variable is not set. Defaulting to a blank string. enter image description here

Error #2: docker-compose : failed to solve: failed to compute cache key: failed to calculate checksum of ref 3f3de231-5630-4e0d-9880-af4d75348d87::bxasqp1metajlwinwtmzknhdf: "/C:\\module\\db": not found enter image description here

This looks very similar to what I faced after upgrading Docker Desktop and changing compose syntax to V2.

  • Error#1 - You can search for an environment variable with "R" in it's value and remove escape characters.
  • Error#2 - You can locate that volume in docker-compose file and add
    "\" at the end.

Make these 2 changes and try running up.ps1 again.

For example:


The solution is to wrap all of your complex values like so:
