So I was curious how to develop terraform providers and runned into an issue i cannot explain.
My CRUD pretty simple, I Create resource and Updating its meta data during lifespan, and Deleting it on destroy command.
func resourceCreate(d *schema.ResourceData, m any) error { id, err := uuid.GenerateUUID() if err != nil { return err } d.SetId(id) return nil}func resourceRead(d *schema.ResourceData, m any) error { return nil}func resourceUpdate(d *schema.ResourceData, m any) error { return errors.New("failed")}func resourceDelete(d *schema.ResourceData, m any) error { d.SetId("") return nil}As you can see Update function returns error, this is my question. I am intentionally failing proccess, but tfstate still updated (i am changing one variable in my resource declaration to see this change).
here is a full resource declaration
func demoResource() *schema.Resource { return &schema.Resource{ Description: "descr", Create: resourceCreate, Read: resourceRead, Update: resourceUpdate, Delete: resourceDelete, // CreateContext: demoResCreate, // ReadContext: demoResRead, // UpdateContext: demoResUpdate, // DeleteContext: demoResDelete, Timeouts: &schema.ResourceTimeout{ Create: schema.DefaultTimeout(10 * time.Minute), Update: schema.DefaultTimeout(10 * time.Minute), Delete: schema.DefaultTimeout(10 * time.Minute), }, Schema: map[string]*schema.Schema{"name": { Type: schema.TypeString, Required: true, Description: "name", }, }, }}What am I missing? I don't think tfstate should be updated after I faield update operation, but it does. I tried both CRUD and CRUDContext methods, in both cases it acts same.
P/S/terraform version Terraform v1.6.5, For provider development used hashicorp/terraform-plugin-sdk/v2/
