Research direction
The error 'The first argument must be one of type string...' indicates that a function expecting a string or Buffer received undefined. This likely occurs in the Elasticsearch driver query building or response processing. Investigate the driver code in the cube js/cube repository (likely in packages/cubejs elasticsearch driver or similar). Check for variables that may be undefined when constructing requests or parsing results. The fix might involve adding default values or null checks.
