Hi guys,

I have tried to install openproject on my raspberry pi 4 (2GB :-( ) today. I follwed the instructions from --> OpenProjectRaspberryPi/index.md at master · madewhatnow/OpenProjectRaspberryPi · GitHub 

After I finished the installation I´ve tried to open the StartPage for the first time, but after some seconds I got an error page (We're sorry, but something went wrong.)

I have searched for the displayed error code at /var/log/apache2/error_log and found following message (besides some "... is not secure: it can be modified by user..." - messages):

[ E 2021-01-16 15:40:57.3214 2124/To age/Cor/App/Implementation.cpp:221 ]: Could not spawn process for application /home/openproject/openproject: The application encountered the following error: Disablde runtime is not defined (ExecJS::RuntimeUnavailable)

the whole error-log is attached to this topic.

The raspberry Pi was installed (today) with the latest Raspberry OS (lite).

Does someone has an idea, what I´ve done wrong?

Thanks in advance and best regards,

Tom
