# Error Indicator and Message

When an error occurs in the flow, the action causing the error is indicated by a red color .  The cause of the error is display in the action settings .  In the example below, the error indicates that the action was expecting an array, but got a string value instead.

Note that the error messages are based on the simulated mock data.

Tips

The actions in green color indicate the path data has taken.  This becomes more important as the flow branches using conditionals such as if/else, match, and switch.
