I couldn't make POST requests to an external suitelet. I am able to make a GET request though. What are the possible issues?

AI generated answer (using internal Slack threads):

If you are unable to make POST requests to an external Suitelet but can make GET requests, there could be several reasons for this: 1. HTTP 405 Method Not Allowed Error: This error occurs when the HTTP method used in the request is not supported for the resource identified by the request URL. If you are getting this error, it means that the Suitelet is not set up to accept POST requests. You can resolve this error by following the steps outlined in this NetSuite SuiteAnswers article: [Resolve Error: "HTTP 405 Method Not Allowed" in Suitelets](https://netsuite.custhelp.com/app/answers/detail/a_id/68637). 2. Suitelet Deployment Settings: Ensure that the Suitelet is deployed with the 'Available Without Login' option checked. This allows the Suitelet to accept requests from external systems. Also, make sure that the 'External URL' option is checked. This allows the Suitelet to be called from external systems. 3. Incorrect Deployment ID: When calling the Suitelet, make sure you are using the actual deployment ID (custdeploy_xxx) and not the internal ID (1). 4. Incorrect URL: When constructing the URL to call the Suitelet, make sure you are not adding the domain into the URL that you get from

url.resolveScript

. The domain is already included in the URL returned by

url.resolveScript
