Today we had to deploy a quickfix to a production environment caused by an error that was solved by Mendix in version 6.10.3 (Tickets 38219, 47089) We migrated form a 6.10.2. version to a 6.10.4. version of Mendix that solved our problem. In return we got another problem. A number of end-users can not login anymore. Looking at the logs we see al lot of errors: Invalid JSONRequest: JSONObject["hybrid"] not found. [User '925188' with session id '1379ad3f-0d7e-40e0-a057-f8301e70c154' and roles 'UserAdmin, UserEdit, ContractEigenaar, PortalManager, PublicatieManager'] I read in another post this is caused by caching. Can this be solved at Mendix server/application side so that we don't have to notify all user for cleaning there browser cache? Most of which don't even know what a browser cache is. We have an on-premise implementation using iis.
We're running into the same issue after upgrading our app through the Mendix Service Console from 5 to 6. Version 6.10.10 is throwing the same error when loading the page and again when trying to log in. Has Mendix replied to your ticket? If so, please update your question.
Invalid JSONRequest: JSONObject["hybrid"] not found. [User 'MxAdmin' with session id 'c934489d-dbeb-43d2-90ef-dfa59576b9af' and roles 'Administrator']
We solved our problem! The app was running on premise and used IIS & Mendix Service Console. IIS was still pointing to the old Mendix version and was using the old mxui.js file rather than the one from version 6.10.10. For us, it was not a cache issue as both the server and browser caches had been repeatedly cleaned up. Below is an image of what we changed to get it to work in our on premise situation.
Perhaps this is the same problem your application is having and getting the newest mxui file solves the issue.
