I am trying to deploy a flow to a sandbox and I am getting the error
Property 'storeOutputAutomatically' not valid in version 48.0
sourceApiVersion specified in my
sfdx-project.json file is 48.0. The
<apiVersion> in our
package.xml is 47.0. However, this flow has contained the
<storeOutputAutomatically> tag for the last month, and has not failed validation for this sandbox. The sandbox has not been refreshed. We have not made changes to the package.xml version or the sourceApiVersion in the
sfdx-project.json file in at least a month.
What could be causing this sudden validation failure?
