This error type is caused when the field type in either the search criteria or columns does not match the formula field type selected (i.e. Text). You can reduce the likelihood of these errors by using the SuiteScript records browser to determine the standard field types to match with the formula field types. For a custom field, simply check the field type under “Customization > Lists, Records & Fields.” Quickly defining why an Invalid Expression error is occurring, and resolving it, gets users back to work. And as the Administrator, it will help answer user inquiries and provide advice to users to mitigate on their own in the future.
