I got the same error earlier today after trying to Deploy to Licensed Cloud Node from Studio Pro. For me, creating a package from Teamserver (in the cloud portal) worked. Also, I was able to Create a Deployment Package in Studio Pro. So I guess trying a couple of different things might get you past this. If it keeps happening, I will file a ticket to get it resolved.
On a side note, its a weird error message. Teamserver shows the Mendix version and of course Studio Pro knows the Mendix version. Maybe a passing issue with the cloud portal.
Hope that helps,
Hi Brian, hi all,
Follow-up: The Issue has been resolved from Mendix side.
I have the same problem since a few days when trying to create a package from the cloud portal. I did not upgrade my app (my mendix version is 9.12.1), the error just appeared when trying to create a new package.
Failed to determine MX version in /workspace/build/source
When I create the package manually via Studio Pro (App → Create Deployment Package) and manually upload it to the cloud node, it works fine.
Has there been an update to the cloud portal that could have this effect?
