Hello All,

Having using FAPI API's for a while for some exploratory work, I have provisioning the FAPI with a password using the following call and used  macro set to PASSWORD set as "1234"

rc = Fapi_Provision(global_fapi_context,PASSWORD,PASSWORD,PASSWORD);


Again tried to clear the TPM using the following calls after doing the FAPI_Initialize.


rc = Fapi_SetAuthCB(global_fapi_context, auth_callback, NULL);
        if (rc != TSS2_RC_SUCCESS){
          printf("Failed to set the callback \n");
        }

        printf("clearing the TPM \n");
        rc = Fapi_Delete(global_fapi_context, "/");
        if (rc != TSS2_RC_SUCCESS){
          printf("Failed to clear TPM\n");
          ret = ERR_FAIL;
        }


But I see the following error,

ERROR:esys:src/tss2-esys/esys_iutil.c:1070:esys_GetResourceObject() Error: Esys handle does not exist (70018).
ERROR:fapi:src/tss2-fapi/fapi_util.c:380:ifapi_set_auth() Set auth value. ErrorCode (0x00070018)
ERROR:fapi:src/tss2-fapi/api/Fapi_Delete.c:377:Fapi_Delete_Finish() ErrorCode (0x00070018) Set owner authorization
ERROR:fapi:src/tss2-fapi/api/Fapi_Delete.c:89:Fapi_Delete() ErrorCode (0x00070018) Entity_Delete
Failed to clear TPM


Any thoughts what went wrong here.
