I want to do a UDM search like this:

email IN %regex_ref_list

The above ref list currently contains only one entry: .*suspiciousdomain.com

The documentation online (

https://cloud.google.com/chronicle/docs/investigation/udm-search#use_reference_lists_in_udm_searches) states that all types of reference lists are supported. However, when trying to run the above search, I get this error:

compilation error validating query: validating reference list: cannot use list regex_ref_list List of type REGEX with function InReferenceList line: 1 column: 1-43 : invalid argument

Why would I be getting this error if regex lists are supported?

Hi @donkos,

As the reference list is of type REGEX, you will need to call it by using "in regex"

Such as:

email in regex %regex_ref_list

Kind Regards,

Ayman
