IpamPrefixesAvailableIpsCreate API throws 'json: cannot unmarshal object into Go value of type []*models.IPAddress' error

Hi,

Below is my sample code.

// Set up NetBox API client
targetPrefix := "192.168.1.0/24" // Change to your desired prefix

client := netbox.NewNetboxWithAPIKey(netboxURL, apiToken)

// Step 1: Find the Prefix ID dynamically
prefixListReq := ipam.NewIpamPrefixesListParams().WithPrefix(&targetPrefix)
prefixListResp, err := client.Ipam.IpamPrefixesList(prefixListReq, nil)
if err != nil || prefixListResp.Payload == nil || len(prefixListResp.Payload.Results) == 0 {
fmt.Println(err)
fmt.Println(prefixListResp.Payload)
fmt.Println(prefixListResp.Payload.Results)
log.Fatalf("Prefix %s not found in NetBox", targetPrefix)
}
prefixID := prefixListResp.Payload.Results[0].ID

// Step 2: Allocate an Available IP from the Prefix
ipReq := ipam.NewIpamPrefixesAvailableIpsCreateParams().WithID(prefixID)
ipResp, err := client.Ipam.IpamPrefixesAvailableIpsCreate(ipReq, nil)
if err != nil || ipResp.Payload == nil || len(prefixListResp.Payload.Results) == 0 {
log.Fatalf("Failed to allocate IP: %v", err)
}

Though the IP address has been created in the netbox, verified via GUI, this API is throwing an error as below.
"Failed to allocate IP: json: cannot unmarshal object into Go value of type []*models.IPAddress"

Is there something wrong in the code above?

Hey,

I'm not seeing this error on v4.2.2-2.

You can see my code here: disc_202_test.go

Maybe my approach is wrong but a few questions for you:

1. What version of the library are you using ?
2. What's the full error message, seems you trimmed something ?

Hi @nutgood,

Thank you. I was using an older version. Once updated to v4.2.2-2, it works fine.
