Composer could not parse version constraint / could not load package (2)

We've stuck in the following error in Drupal CI/CD (again).

Composer require failure - View results on dispatcher

  Could not parse version constraint ^0.14.*: Invalid version string "^0.14.*"  

Our K8s (Kubernetes) module is depending on the library maclof/kubernetes-client, which was updated from 0.14.3 to 0.15.0 just while a day ago. Therefore I created a patch to fix the version of maclof/kubernetes-client at #3084185 as follows:

   "require": {
-    "maclof/kubernetes-client": "^0.14.*"
+    "maclof/kubernetes-client": "~0.15"
   }

However it is still getting failure. It looks Drupal CI/CD keep using the prior composer.json (version ^0.14.*)according to the log.

We didn't update our composer.json this time and the third-party library maclof/kubernetes-client hasn't newly released.
The database should be ~0.15.
