web client is not showing the data structures

[kindredally]

Building the dashboard demo using instructions and code from latest github. The json data does not appear on the dashboard. It shows no data in json file... Is there some build option I am missing ...its like something is not getting generated. What can I check?
Thank you.

It is okay to close this. But, I might suggest something be added to the scripts to check the environment is setup correctly, specifically for the project directory ci. I missed it. I have now installed all the latest packages and its building with no errors. I had to modify preBuild.py (removing the ../):
elif isinstance(item, tuple) and item[0] == "CONFIG_PATH":
copyfile(env.get("PROJECT_DIR") + '/' + item[1], 'gui/js/configuration.json')
elif isinstance(item, tuple) and item[0] == "DASHBOARD_PATH":
copyfile(env.get("PROJECT_DIR") + '/' + item[1], 'gui/js/dashboard.json')
elif isinstance(item, tuple) and item[0] == "DOMAIN_LIST":
domains = item[1]
elif isinstance(item, tuple) and item[0].lower() == "openssl":
openssl = item[1]
and I added the empty subdirectory 'include'
