GUI internal server error

[Flomb]

i can not use the GUI, it is answered with a 500 internal server error.
Apparently a file is missing, maybe i misunderstood the install instructions. I used:

git clone https://github.com/dirkjanm/ROADtools.git
pip3 install roadlib/
pip3 install roadrecon/

Error Message:

─$ roadrecon gui -d roadrecon.db --debug

There is no pre-built version of the gui included in the source code on git. You can either:

• Download a pre-built release from the latest version on Azure Pipelines (current latest version here: https://dev.azure.com/dirkjanm/ROADtools/_build/results?buildId=1037&view=artifacts&pathAsName=false&type=publishedArtifacts)
• Build the gui manually if you have npm installed

Instructions for both these steps are in the readme
