A random build was incorrectly promoted to production

I was experimenting with putting non-string values for env vars in now.json; I made a variable called VUE_APP_FOO under the build env vars, and tried to give it an array value like:

"VUE_APP_FOO": ["foobar", 123]

When trying to deploy with the now command, it predictably failed with this error:

Error! The property build.env['VUE_APP_FOO'] in now.json can only be of type String.

I changed the value to a number instead of an array, and it failed again with the same error. After those two experiments, I made the value a string (actually, it was the array again, but JSON-encoded) and ran now one more time. This time, I unexpectedly got this warning:

WARN! This is the first deployment in the [my project name] project. It will be promoted to production.

Sure enough, it became the new production build on the domain after it finished building. It definitely wasn’t the first build for the project, and I didn’t change the name or anything, only that environment var. Was it because the previous two builds failed? Or was it totally random?

Sure thing. Sent!

Gotcha. Thanks for the details! We’ll take a look why this is happening.

It should not be.
