Start by reading sfdx/convert-examples-to-sfdx.sh and reproduce the ./convert-examples-to-sfdx.sh command from the sfdx directory. Trace the force:mdapi:convert failures and the subsequent force-app/main/default copy errors; done means the script completes without InvalidPackageDirectory or missing-directory errors and reports a successful conversion.
