[SalesForce] SFDX: ERROR: INVALID_OPERATION: rollbackOnError option must be true on a production org. When using Salesforce DX pre-release and Visual Studio Code

Your command is using the wrong value for the -d parameter. It should be the folder that your metadata is in, not the top-level project folder.

For example, if you create a new project in P:\emailStatus, the create project command will add P:\emailStatus\force-app by default where all of your metadata is stored. If you want to create a package version from that, you would use sfdx force:package:version:create --package "emailStatusUpdate" -d force-app -x.

If you have your metadata in a different folder (e.g., P:\emailStatus\core) you would pass that folder name instead.

I've found this reference to be helpful for understanding the package flow. It gives the order of the commands with examples.

You have two choices. First, you can use force:package commands to create an unlocked package. You can install this in production with force:package:install; it is similar to installing an AppExchange package. Otherwise, you would need to use force:source:convert to get a mdapi style format, then use force:mdapi:deploy with the relevant test level (e.g. RunLocalTests) and set rollbackOnError to true. Check out the Salesforce CLI Reference for specific details, or sfdx help force:<command> for command-level help direct from the console. I do not believe that you're currently allowed to create unlocked packages directly via the GUI, but you can open a terminal by using the Terminal > Create New Terminal option, which will open a sfdx environment by default.
