Symptoms

When creating or updating an Extraction with a backslash in a regular expression field (such as prefix), the backslash is incorrectly removed.

Impact

The backslash is incorrectly removed.

Conditions

An Extraction is created or updated with a backslash in a regular expression field (such as prefix)

Workaround

Regular expression in extracts can be defined with double backslashes wherever a literal backslash is needed. The extra backslash must be added upon each update to the extraction.

Fix Information

When creating or updating an Extraction with a backslash in a regular expression field (such as prefix), the backslash is no longer incorrectly removed.
