has_error

Synopsis​

@has_symbol([String]) -> Boolean

@has_symbol([InnerFunction]) -> Boolean

Description​

Checks whether a backend reported an error for an object.

info

Available in Contextal Platform 1.0 and later.

Parameters​

An optional argument allows for matching the exact error string (with a 'String' value) reported by a backend, or inside that string using inner functions regex/iregex/starts_with.

Return value​

Boolean: true if an error was reported, false otherwise.

Examples​

@has_error()
  • This will match objects, for which errors were reported.
note

The error messages are backend specific and there is no common standard here. For example, the Email backend can report a following error message:

"error": "Invalid data (Truncated or otherwise invalid mail)"

to match objects with this error, you can use a query like:

object_type == "Email" && @has_error(regex("Truncated"))
