Troubleshooting UPark API Error 500 on parking kiosks after vandalism. Includes diagnostic steps, safety warnings, and prevention tips for reliable operation.
Detailed logs are crucial for pinpointing the root cause. Provide error codes and timestamps.
A recent update may have introduced bugs or compatibility issues.
Understanding the network configuration helps isolate network-related problems.
500 typically indicates a server-side issue, however, physical damage to the kiosk can trigger API errors. Vandalism can disrupt the 24V DC power supply, leading to intermittent failures or complete system shutdown. Damage to the bill validator can cause incorrect data to be sent to the API, resulting in an error. Communication errors can stem from damaged ethernet or serial cables impacting data transmission. Solenoid locking mechanisms, if forced open during vandalism, may report incorrect status via the API.
High voltage (24V DC) is present within the kiosk. Do NOT attempt to repair or replace internal components without proper training and authorization. Isolate power before performing any maintenance. Lockout/Tagout (LOTO) procedures are mandatory before any internal access or repair is performed. Ensure adequate ventilation while the kiosk is powered on to prevent overheating.
Check the kiosk's internal real-time clock (RTC) battery. Vandalism events can often lead to power loss that can deplete the RTC battery, causing inaccurate time stamps and API errors. Replacing the RTC battery can resolve intermittent communication problems.
