We have a java application that connects to ExactOnline for performing the operations. The connection works fine for almost 9days and then it will start complaining about the below exception:
"Request from start.exactonline.nl returned an error (response code: 400, response: { "error":"invalid_grant","error_description":"Token is not allowed, because of invalid or empty chainId"
After encountering this error we have to force re-authorize the application by the user to get the new accessToken.
Any help would be appreciated.
