Scratch Org Feature not Enabled using Org Shape

Summary

When using the Org Shape (beta) feature, sometimes the ContactsToMultipleAccounts feature from the source org isn’t enabled in the target scratch org.

Steps To Reproduce:

1. Create an Org Shape from an Org that has the ContactsToMultipleAccounts Feature enabled
2. Create a new SFDX Project and use the Org Shape in the project-scratch-def.json:

{
  "orgName": "bug-org",
  "sourceOrg": "00Dj0000000SOURCEORGID"
}

1. Create a scratch org using the CLI: sfdx force:org:create -f config/project-scratch-def.json -a feature-bug

Expected result

When the scratch org is created, it has the ContactsToMultipleAccounts Feature enabled and allows pushing code that relies on this feature (Presence of the AccountContactRelation object exists)

Actual result

Sometimes the feature is enabled, and sometimes it isn’t. It’s not clear when it is or is not enabled in the Scratch Org. In come cases:

• The UI and the Account.settings metadata will indicate the setting is enabled, but pushes will fail (lack of AccountContactRelation Apex class)
• The UI and Account.settings metadata indicate the feature is NOT enabled, (pushes also fail)
• The UI and Account.settings metadata indicate the feature is enabled, AND pushes work

We observe the issue each time when we try to push Apex code into the org that relies on the AccountContactRelation object that only exists when this feature is enabled and the push fails.

The issue seems to present itself randomly. More than half of the scratch orgs we create in this way are unusable. We only started to see this issue a few weeks ago following the Spring '21 release of SalesForce.

For anyone interested there are 2 Known Issues about it, one for Org Shape here, and a second one for Scratch Org here (because the issue is actually not limited to Org Shape).

This is a known serverside issue and the appropriate team is tracking internally with W-9529783 and W-9604466. Since this is not an issue with the CLI I’m closing this issue. Feel free to contact support for anything addtional.
