“code”: “UNEXPECTED_ERROR”, “message”: “Cannot invoke \”com.netledger.core.session.NLSession.getCompany()\” because the return value of \”com.netledger.app.site.hosting.restlet.getNLSession()\” is null” what is possible reason trigger this error on restlet invokation?

AI generated answer (using internal Slack threads):

The error message you're seeing is indicating that the method

getNLSession()

is being invoked on a null object. This is likely because the method

getNLSession()

is being called before the session has been properly initialized. In the context of a RESTlet, this could be due to a few reasons: 1. Session Initialization: The session might not have been properly initialized before the

getNLSession()

method is called. Make sure that the session is correctly initialized before making this call. 2. Concurrency Issues: If multiple threads are trying to access the session at the same time, it might result in one thread getting a null session. Make sure that the session handling is thread-safe. 3. Session Timeout: If the session has timed out before the

getNLSession()

method is called, it would also result in a null session. Make sure that the session timeout settings are appropriate for your use case. 4. Incorrect API Usage: If you're using an API that is not supported in the context of a RESTlet, it might also result in this error. For example, in one of the threads, a user was trying to use

nlapiGetWebContainer()

in a RESTlet, which is not supported. Remember to always check the return value of a method before invoking another method on it to avoid null pointer exceptions. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
