Errors while adding TRUECHART extension

Error Code : Service request failed with error code : 400 Action : getFrontendSession

Possible Cause 1

Missing trueChart.json config file 

How to Check :

Verify if the trueChart.json config file exists in path 

C:\Program Files\Qlik\Sense\BrokerService\service-configs\trueChart.json file

Solution/Workaround : 

Recreate the missing config file with the parameters and restart the service dispatcher 

{"identifiers":["trueChart"], "port": "8080"} 

Port might change if something different is specified during the installation.

We delete this file only on a uninstallation And create it on install.
