If you experience errors while opening wizards in the front end user interface, Ensure the wizard files are accessible and comply to the required format. Check the browser development console for any error or warning messages.

When using the /start_project API endpoint to start optiSLang projects, the optiSLang Web Service waits a certain amount of time for the project to report back. This time is defined by the start_timeout configuration setting and can be overridden by the optislang_start_timeout starter script return value. When the time expires without the project having reported back, optiSLang Web Service reads the error log file defined by the error_log_file starter script return value and returns it to the front end user interface. This can be used to debug or notify users about project start errors. Additionally, Python scripts may use print statements or exceptions to pass and display errors and additional information in the front end user interface.
