Persistent 'Undefined' API Version Error When Sending Device Command via Azure IoT Central"

[mehrdad2334]

We are trying to send a command to an IoT device using Azure IoT Central, specifically the DisplayText command on the device with ID ---------. Despite following the API documentation and making various attempts, we consistently receive an error indicating that "undefined" is not a valid API version.

Steps Taken:

Obtained Access Token: Successfully obtained a valid access token using OAuth 2.0.

Set Up Postman Request: Created a POST request in Postman to send the DisplayText command.

Correct URL: Used the URL format as per the Azure documentation.

API Version Tried: Attempted to use multiple API versions, including 1.1-preview and 2022-07-31.

Headers and Body: Ensured the headers (Authorization and Content-Type) and the JSON payload in the request body were correctly set.

Persistent Error: Despite these steps, we consistently receive the error:

"error": {
"code": "NotFound",
"message": ""undefined" is not a valid API version."
}
Specific Error Message:

"error": {
"code": "NotFound",
"message": ""undefined" is not a valid API version. You can contact support at https://aka.ms/iotcentral-support. Please include the following information. Request ID: , Time: "

}
Request for Assistance: We seek guidance on the correct API version or any additional configuration required to successfully send the command to the IoT device. Any insights or support from Azure SDK for Go community would be greatly appreciated.

@mehrdad2334, as you are invoking API directly for your ask, to better understand your ask, do you plan to use Azure GO SDK package for your scenario and ask us for the correct API version?
Could you share the link of the API documentation?
