SXA Search Boosting Throws Error

Question

I have configured the search scope for SXA (Sitecore 9.3) and it works as expected. However, when I try to add boost configuration to the search scope it throws the below error.

Invalid Method Call Argument Type: Field - FieldNode - Field: _name - System.String. Only constant arguments are supported.

It happens with any field added in the boost configuration.

The search query works again if I remove all the rules. The error in the log file is below:

26380 20:12:20 WARN  Results endpoint exception
Exception: System.NotSupportedException
Message: Invalid Method Call Argument Type: Field - FieldNode - Field: _name - System.String. Only constant arguments is supported.

Any help is appreciated.

Answer 1

I ended up opening a support ticket with Sitecore and they identified this as a known bug.

The hotfix I received today is SC Hotfix 418336-1 SXA 9.3.0.2589.

Consider contacting them for the latest hotfix, as it may include other fixes to SXA.
