but whent i try to upload zip file and processing the build.,
showing this error
UserError: Error: CordovaError: Failed to fetch plugin cordova-plugin-purchase via registry. Probably this is either a connection problem, or plugin spec is incorrect. Check your connection and plugin name/version/URL. This could be caused by a problem with a different plugin.
this my config.xml
<plugin name="cordova-plugin-purchase" source="npm"> <variable name="BILLING_KEY" value=###" /> </plugin>
