Overview
The message indicates that the Find Text Action has experienced error, e.g., the system has run out of memory.
Event examples
See some examples of the Find failed Event messages:
- Task "Daily invoicing" Action "Find Text" failed. Error: Invalid lookbehind assertion encountered in the regular expression.
- Action "Find Text" failed. Error: Invalid preceding regular expression prior to repetition operator. The error occurred while parsing the regular expression.
- Error: Found a closing ) with no corresponding opening parenthesis. The error occurred while parsing the regular expression fragment.
- Error: Unmatched [ or [^ in character class declaration. The error occurred while parsing the regular expression.
Cause
A possible cause of the error is that an unusual search is performed in which either the text that is being looked for or text string in which the search is conducted is extremely big.
When the Invalid lookbehind assertion encountered in the regular expression error is logged, it indicates that Automation Workshop encountered a variable-length lookbehind assertion that it does not fully support.
Solution
When the error is related to invalid Regex syntax, please refer to Regex (Regular expressions) explained, which includes workarounds for variable-length lookbehind assertions.
If error persists and there is no explanation about possible causes, try restarting computer and run the Task again.
