AWS Glue and Databricks SQL endpoint

Hello, we're receiving an error when running glue jobs to try and connect to and read from a Databricks SQL endpoint.

An error occurred while calling o104.load. [Databricks][DatabricksJDBCDriver](500051) ERROR processing query/statement. Error Code: 0, SQL state: TStatus(statusCode:ERROR_STATUS, infoMessages:[*org.apache.hive.service.cli.HiveSQLException:Configuration dbtable is not available.:48:47, org.apache.spark.sql.hive.thriftserver.HiveThriftServerErrors$:hiveOperatingError:HiveThriftServerErrors.scala:65, com.databricks.sql.hive.thriftserver.thrift.ErrorPropagationThriftHandler:runSafely:ErrorPropagationThriftHandler.scala:124, com.databricks.sql.hive.thriftserver.thrift.ErrorPropagationThriftHandler:ExecuteStatement:ErrorPropagationThriftHandler.scala:73, org.apache.hive.service.cli.thrift.ThriftCLIService:ExecuteStatement:ThriftCLIService.java:429, org.apache.hive.service.rpc.thrift.TCLIService$Processor$ExecuteStatement:getResult:TCLIService.java:1437, org.apache.hive.service.rpc.thrift.TCLIService$Processor$ExecuteStatement:getResult:TCLIService.java:1422, org.apache.thrift.ProcessFunction:process:ProcessFunction

The same read() query with the same options() works fine if I run it in a local pyspark cluster, but its failing in Glue. I suspect it could be related to the GlueContext - has anyone run across this issue or have an idea what might be causing it?
