Current provider version has a known bug:

GKE Terraform Node Pool Update Failure
Issue: A customer experiences "Error: googleapi: Error 400:" when updating a GKE node pool using Terraform, due to an outdated Terraform provider (google-beta_v4.85.0). The provider incorrectly attempts to clear a kubelet_config field, which the GKE API rejects. The issue stems from an incompatibility between the old provider and a new computed field introduced in newer versions.
