Disable the notification on the Change node.
Once the infrastructure for validation error messages is implemented
this can be re-enabled and retrofitted to the
new structure.
This change adds input validation to the gui of Change Nodes to prevent
the user from unintentionally entering an invalid regular expression
(in case the ‘use regular expressions’ option is enabled).
The user will be notified (using the RED notification mechanism) on the
specific error code to help resolve the issue.
Make logging of erratic regular expressions more verbose to help
identification and resolving of the configuration issue:
eg.:
old: 24 Dec 18:40:09 - [error] [change:Strip kW] Invalid regex: *kW
new: 24 Dec 18:40:09 - [error] [change:Strip kW] Invalid regular
expression: /*kW/: Nothing to repeat
old: 24 Dec 20:15:57 - [error] [change:Strip kW] Invalid regex: *kW
new: 24 Dec 20:15:57 - [error] [change:Strip kW] Invalid regular
expression: /[kW/: Unterminated character class
This change adds input validation to the gui of Change Nodes to prevent
the user from unintentionally entering an invalid regular expression.
The user will be notified on the specific error code to help resolve
the issue.
Adding exception handling to the change node to prevent node-RED from
crashing on invalid regular expressions eg. “*kW” (missing escape
before the asterix)
