I just updated my Adobe ColdFusion (ACF) 2021 to update 20 and I started receiving the following error, when trying to execute Testbox tests individually:
Function Runremote Does Not Support opt_run as an Argument
ACF update 19 didn't have this behavior.
What's the fix?
ColdFusion 2021 Update 20 adds a new JVM flag:
-Dcoldfusion.runtime.remotemethod.matchArguments
The flag defaults to true, which means that every remote CFC method must receive only the arguments that are explicitly declared with <cfargument> (or in the function header). If an extra named argument sneaks in, ColdFusion now throws an exception.
To fix this, you have a few options:
1. Add any missing arguments to your methods to prevent the exception from firing.
2. Stop passing extra arguments to methods that aren't explicitly declared.
3. In ColdFusion Administrator » Java & JVM (or jvm.config) add:
-Dcoldfusion.runtime.remotemethod.matchArguments=false and restart CF services.
4. If you're using CommandBox, disable this new "feature" by adding the following to your server.json file:
"jvm":{
"args":[
"-Dcoldfusion.runtime.remotemethod.matchArguments=false"
]
}
Note: As pointed out by @happysailingdude, the hyphen (dash) at the beginning of the JVM argument is very important. Please don't forget about it.
