Impark Reef App Damage Details Retrieval Error... | terminalfaults.org

Technical Background:

The application relies on HTTPS for secure communication with the server to retrieve damage details. The API endpoints return JSON formatted data. A failure in TLS/SSL handshake, incorrect API response codes, or JSON parsing errors can lead to the reported issue. DNS resolution failures may also contribute. Token-based authentication could be malfunctioning.

Symptoms:

The Impark Reef app fails to display parking meter damage details, presenting a 'damage details retrieval error'. This issue prevents users from accessing necessary information regarding reported damage.

Possible Causes:

Expired or invalid TLS/SSL certificate on the server, preventing a secure connection.
Incorrect API endpoint configuration within the app, leading to requests being sent to the wrong location.
Server-side API errors (e.g., 500 Internal Server Error, 404 Not Found) which the app is not handling gracefully.
JSON parsing errors within the app due to malformed data received from the server.
Token authentication failure, preventing the app from accessing the required data.
DNS resolution failure, impacting the app's ability to locate the server.

Solution:

1

Verify the server's TLS/SSL certificate is valid and not expired using an online SSL checker.
2

Review the API endpoint configurations within the Reef app's settings (if accessible) or configuration files on the server to ensure they are correct and up-to-date.
3

Monitor server-side logs for any API errors (500, 404, etc.) that correlate with the app's failure to retrieve damage details.
4

Validate the JSON data returned by the API endpoint using a JSON validator to ensure it's well-formed and conforms to the expected schema.
5

Check the app's authentication token validity and renewal process. Ensure the token is being properly refreshed and passed with API requests. Investigate potential OAuth issues.
6

Flush the DNS cache on the device running the app. If the device is connected via a network, flush the network DNS cache as well. On Android, this can often be found in Settings -> General management -> Reset -> Reset network settings. Note this resets wifi passwords.
7

Clear the app's cache and data in the device settings. This removes any potentially corrupted cached data.

Safety Warning:

Ensure the kiosk is in a stable state before performing any software updates or configuration changes. Maintain a dry surface around the kiosk. If the kiosk requires a power cycle, use Safe Handling: unplug the power cord and allow 30 seconds before re-connecting.

Prevention:

Implement robust error handling within the app to gracefully manage API failures and display informative messages to the user. Regularly monitor the server's TLS/SSL certificate and API endpoints for issues. Implement automated testing to detect regressions in API functionality. Implement automated token refresh.

Expert Tip:

Use a network packet analyzer (e.g., Wireshark on a test device) to inspect the network traffic between the app and the server. Examine the HTTP request and response headers to identify any potential issues with the connection or data transfer. Review the server's CORS configuration.

Frequently Asked Questions

•Are other app features functioning correctly?

This helps isolate whether the issue is specific to the damage details retrieval or a broader app problem.

•Have there been any recent server-side code deployments?

Recent code changes may have introduced bugs affecting the API endpoint.

•Is the issue reproducible on multiple devices or a specific device?

Helps determine if the problem is device-specific or widespread.
