Cannot show history and graph

[jeppefugl]

I have downloaded the Raspberry Pi image and updated to latest version of Jeedom. I recieve data from mysensor node and weather data.

I cannot get the history module to load any graph. I get the following javascript error.
“Unable to get property 'chart' of undefined or null reference” in file getJS.php line 151

I can see the data available when exporting to csv.

Can anybody give me a hint to solve this?

I have asked the same question on the jeedom forum - https://www.jeedom.fr/forum/viewtopic.php?f=54&t=12837
