First of all, my English is not good. So, I hope you understand this. I study about mendix how to use mindsphere data. and i use guidline that is “Build a MindSphere app with Mendix”(url : https://academy.mendix.com/link/path/80/Build-a-MindSphere-app-with-Mendix). Have followed guideline that is Ch6”.Adding a Time Series Chart”, Something went wrong. That is timeseries doesn't work well(What I want to do is show a timeseries chart corresponding to the asset.). I've been trying for 10 hours to solve this problem but couldn't…... First of all, the things I set are as follows. *mendix version : JSON structure 2. Import mapping & Domain model 3. Microflow 4. Access permission 5. Timeseries property & Timeseries item property 6. This is the result of running locally 7. Error befor click the asset button & Error after click the asset button I have confirmed that timeSeriesdata exists. I thought of two cases where the problem occurred. 1. microflow - I try : I thought that microflow couldn't get the timeseries data properly, so I tried the guidline several times as described, but the result was the same. 2. My inexperienced timeseries widget usage How can I fix it? And I would appreciate it if you could tell us how to use the timeseries widget :)
