# 😖 Errors
Chevereto application errors can happen by several causes, including server issues. In a multi-layered system like Chevereto is crucial to understand when an error is caused by Chevereto and not something else.

# Error Id
✅ Chevereto logs all error events under a unique errorId associated with the error stack trace and debug information.
<some code>: ** errorId #dacb7f96fb9fd28d **
Errors in Chevereto are hidden by default, the public part is the error identifier. Errors won't be displayed for security reasons and the error identifier is a randomly generated unique identifier per error event.
✅ In no situation the error id will provide any relevant information about the error happening.
💡 The error id exists for lookup for that error in the system error log device.
# Stack Trace
All errors include the full call stack trace. This is a list of files accessed to process the application logic.

# It is Chevereto related?
Chevereto runs on top of many technologies working at the same time and any component of this stack could fail.
💡 It is likely that Chevereto won't cause any of the following issues:
- Unable to connect (network issues)
- MySQL server gone
- CORS (missing icons, fonts)
- Cookies/Sessions not working (permissions)
- Restricted functions (
- Server restrictions (
- Wrong handling the user real connecting IP
To determine if an issue is Chevereto/System related may be complicated for most users. We recommend purchasing Extra Support (opens new window) if the issue needs urgent attention in your organization.
# Common errors
# HTTP 500 - Internal Server Error
This is a generic error response emitted by the web server layer and this it indicates the existence of an error, but it doesn't specify any concrete explication for it. As these errors may spawn in any layer, it is recommended to check the system error log device.
💡 These errors must be debugged in the Web server layer, which will vary depending on the web server software. Always refer to your web server provisioning documentation.
Once the cause for the HTTP 500 error is known, you can either solve the situation with our own means or request help from us.
# Something went wrong
This message indicates an error caught by Chevereto, but hidden as per system settings. To know what is going on you have to either look for the logged error against the provided error id or use XR Debug to catch the error as it happens.

# Dumped update query
/install you see a plain text message starting with
#Dumped update query it means that you MUST manual run the printed queries in your MySQL console.
💡 If dump update query (opens new window) setting is enabled or if the images table has more than 1,000,000 records, Chevereto will dump the SQL statements required to carry the database update which must run direct in the MySQL console. Chevereto has this functionality to minimize breaking your large database as the process could take several minutes to complete.
