I'm stumped on this one. I get that the error has to do with an API version mismatch, but as far as I can see everything is on the same version.
I'm trying to pull an unmanaged package from my sandbox using
force:mdapi:retrieve, so that I can extract the package.xml file and use it with the new
sfdx force:source:retrieve CLI command, which was released in Winter '19.
My Sandbox API is 44.0 (highest selectable version for an Apex class in dev console).
My SFDX Project API is 44.0 ("sourceApiVersion":"44.0" in sfdx-project.json). It's a new project created today expressly to test this.
My VSCode Salesforce Extension Pack is v44.11.0
Here's what I got in my VSCode terminal:
PS P:\SpreadsConsolidation> sfdx force:mdapi:retrieve -p "Spreads Consolidation" -s -u fullcopy -r ./mdpkg Retrieving source... ERROR: UNSUPPORTED_API_VERSION: Invalid Api version specified on URL.
-a 44.0 flag got the same error.
What am I missing here?
