YamlParsing Error while calling FindYamlByPath function in harness-go-sdk

[snp1606]

Hi Team,
I am trying to update my harness-go-sdk version from 0.1.11 to 0.3.9 and in one of our terraform module its failing on the terratest.
Below are the details . Please check the details and suggest the fix/resolution for doing the backward compatibility while upgrading the harness-go-sdk version.
I have checked the arguments passed to FindYamlByPath which are 'id' and 'path' and they are getting valid values. Please let me know if you need any further information from the code to reproduce the error.

# The line which gives error
workflowYamlItem err := client.ConfigAsCodeClient.FindYamlByPath(fmt.Sprint(applicationAttributes["id"]), cac.YamlPath(path)

# Error message :
panic: runtime error: invalid memory address or nil pointer dereference [recovered]
panic: runtime error: nvalid memory address or nil pointer dereference

# Client Configuration for Harness

client, err := cd.NewClient(&cd.Config{
AccoundId: helpers.EnvVars.AccountId.Get(),
APIKey: helpers.EnvVars.ApiKey.Get(),
Endpoint: "https://app.harness.io/gateway",
DefaultHeader: make(map[string]string),
HTTPClient: &retryablehttp.Client{

RetryWaitMin: 5 * time.Second,

HTTPClient: &http.client{

},
Backoff: retryablehttp.DefaultBackoff,
CheckRetry: retryablehttp.DefaultRetryPolicy,
}
DebugLogging: true,
})
