[arthur-trt]

Expected Behavior

Trying to write a secret-id of an approle.

Current Behavior

Have a json unmarshall error

Failure Information

Vault binary -> hashicorp/vault:1.15.6
Vault client go -> github.com/hashicorp/vault-client-go v0.4.3

Steps to Reproduce

func writeAppRoleSecretID(
	ctx context.Context,
	client *vault.Client,
	name string,
) (*schema.AppRoleWriteSecretIdResponse, error) {
	response, err := client.Auth.AppRoleWriteSecretId(
		ctx,
		name,
		schema.AppRoleWriteSecretIdRequest{},
		vault.WithMountPath(Config.Content.Vault.Path.AppRole),
	)

	return &response.Data, err
}

error(*encoding/json.UnmarshalTypeError) *{Value: "number", Type: reflect.Type(*reflect.rtype) *{t: (*"internal/abi.Type")(0x104d2cd60)}, Offset: 263, Struct: "AppRoleWriteSecretIdResponse", Field: "data.secret_id_ttl"}

This function will failed because of unmarshall error

Additional Information

curl -s -H "Content-Type: application/json" -H "X-Vault-Token: ${VAULT_TOKEN}" -X POST ${VAULT_ADDR}/v1/auth/approle/role/test/secret-id | jq
{
  "request_id": "945f92f6-79f7-b119-4dfe-f2dcf2447bf6",
  "lease_id": "",
  "renewable": false,
  "lease_duration": 0,
  "data": {
    "secret_id": "b62f3dc0-ecad-08b1-6ae8-c81ca02bb22f",
    "secret_id_accessor": "5298cfca-a7eb-052d-c77f-a647eff4b5f3",
    "secret_id_num_uses": 0,
    "secret_id_ttl": 0
  },
  "wrap_info": null,
  "warnings": null,
  "auth": null
}

When using curl, we can see .data."secret_id_ttl" is a number and not a string. But the API Explorer shown on my vault set secret_id_ttl as a string :

{
  "secret_id": "string",
  "secret_id_accessor": "string",
  "secret_id_num_uses": 0,
  "secret_id_ttl": "string"
}

The probleme is also present on AppRoleReadRoleResponse and could be on other response schema
