Error messages and the standard error format

If your application does not handle an error, ColdFusion displays a diagnostic message in the user's browser.
Error information is also written to a log file for later review. (For information on error logging, see Logging errors with the cflog tag.)
The standard error format consists of the information listed in the following table. ColdFusion does not always display all sections.



Error description

A brief, typically online, description of the error.

Error message

A detailed description of the error. The error message diagnostic information displayed depends on the type of error. For example, if you specify an invalid attribute for a tag, this section includes a list of all valid tag attributes.

Error location

The page and line number where ColdFusion encountered the error, followed by a short section of your CFML that includes the line. This section does not display for all errors. In some cases, the cause of an error can be several lines above the place where ColdFusion determines that there is a problem, so the line that initially causes the error might not be in the display.


Links to documentation, the Knowledge Base, and other resources that can help you resolve the problem.

Error environment information

Information about the request that caused the error. All error messages include the following:

  • User browser
  • User IP address
  • Date and time of error

Stack  trace

The Java stack at the time of the exception, including the specific Java class of the exception. This is helpful if you must contact Adobe Technical Support.The stack trace is collapsed by default. Click the heading to display the trace.


If you get a message that does not explicitly identify the cause of the error, check the key system parameters, such as available memory and disk space.
