#Error codes

Each validation problem has a JSON path, a code, and a localized message.

#Scenario validation

Code	Meaning
`type`	Wrong value type.
`required`	Missing required field or parameter.
`unknown-field`	Unknown format-2 field or behavior parameter.
`enum`	Value outside the allowed choices.
`range`	Number outside its allowed range.
`version`	Unsupported `formatVersion`.
`id`	Invalid identifier syntax.
`address`	Malformed or out-of-range individual, line, or group address.
`duplicate`	Duplicate identifier or address.
`reference`	Reference to a missing line, channel, object, coupler, or topology level.
`port`	Port not accepted by a behavior, or an invalid channel association.
`dpt`	Unsupported DPT or DPT incompatible with a port.
`association`	Incompatible payload sizes on one group address.
`no-ga`	A control action refers to an object without a group address.
`toggle`	`"toggle"` used with an object that is not one bit.
`conflict`	Mutually incompatible actions or topology settings.
`incompatible`	Button, input, or equipment incompatible with its behavior.
`unknown-behavior`	Behavior ID has not been registered.
`unknown-equipment`	Equipment type has not been registered.
`unknown-room`	Referenced room is not declared in `rooms`.
`format`	A text value does not have the expected format, such as `clock.start`.

#During simulation

Code	Meaning
`extension-error`	An extension threw an exception; the simulation pauses.
`cascade`	Too many events occurred at the same simulated time.
`incompatible-command`	Equipment cannot apply a behavior's output command.
`no-ga`	A send was requested for an object without a group address and was ignored.
`view-error`	An equipment view failed; a warning frame replaces it while simulation continues.

#Configuration warnings

These warnings do not stop the simulation. They are shown above the diagram, and in getState().diagnostics, when a parameter that compensates a property of the load disagrees with that property. A scenario can keep such a mismatch on purpose to illustrate a commissioning error.

Code	Meaning
`config-valve`	The heating actuator output (`valveType`) and the connected radiator valve (`normallyOpen`) disagree; the valve opens when no heat is requested.
`config-wiring`	The shutter actuator output inversion (`invertOutput`) and the motor wiring of the shutter (`wiringReversed`) disagree; the shutter moves opposite to the commands.
`config-contact`	The window contact type (`contactType`) and the input inversion (`invert`) disagree; open and closed are reported the wrong way round.
`config-datatype`	A group address links DPTs of the same size but different meaning, such as a scene number (17.001) and a percentage (5.001), or 5.001 and 5.004. One-bit DPTs are not compared.
`config-polarity`	A group address links DPT 1.009 (1 = closed) and DPT 1.019 (1 = open), whose values have opposite meanings.
