HUBS-1815 | Terraform - VDB update call fails when appdata_source_params are absent

[Uddipaan-Hazarika]

Context:

Terraform - VDB update call fails when appdata_source_params are absent.
https://delphix.atlassian.net/browse/HUBS-1815

Problem:

We were not specifying the field appdata_source_params as computed. And we were setting this field in the state file. So when we dont provide any value to the field(non-appdata), it was setting “null“ in the statefile. So any update call would change the string “null” → null. Which is not accepted as the param is a string. Hence, it failed.

resource_vdb_group_test.go:15: Step 1/1 error: After applying this test step, the plan was not empty.
        stdout:
        Terraform used the selected providers to generate the following execution
        plan. Resource actions are indicated with the following symbols:
          ~ update in-place
        
        Terraform will perform the following actions:
        
          # delphix_vdb.new will be updated in-place
          ~ resource "delphix_vdb" "new" {
              - appdata_source_params  = "null" -> null
                id                     = "11-ORACLE_DB_CONTAINER-8"
                name                   = "DBOMSRFB555Erhel8397k8qar8_MZ3"
                # (14 unchanged attributes hidden)
            }
        
        Plan: 0 to add, 1 to change, 0 to destroy.

Solution:

Added the computed flag. Now appdata_source_params doesn't gets set when we dont specify it. It is treated as a computed field if not set explicitly.
