Issue

When building a Native Mobile application, the iOS Build fails with the following:

In the log files located in the %LOCALAPPDATA%\Mendix Builder\logs folder, the following errors will be present:

(error) [appcenter] 'Unable to replace configuration for app xxx for branch master...'
(error) [console] 'Request failed with status code 400'

For more information on finding these logs, refer to the How to find the Native Builder logs KBA.

Environment

Native Mobile

Cause

The most likely cause in this case is that the provisioning profile and/or the certificates are expired.

When these have expired, App Center will reject the build and the build will fail.

Solution/Workaround

The solution is to update the provisioning profile (as mentioned in Install Provisioning Profile) and/or the certificates (as mentioned in Create, export, and delete signing certificates). Once these have been updated, the application should build without issues.
