Hi All,

We have a Postgre SQL DB connected to Appian system, and we are trying to fetching the data from respective table.

i created CDT, entity mapping verified & Data store published successfully. In Rule Expression, when we tried the query entity for this DSE, we are getting below error. 

Expression evaluation error at function a!queryEntity: An error occurred while retrieving the data. Details: Unexpected error executing query (type: [AAFAssetDT2555], query: [queryentity expression], order by: [[Sort[assetpreviousstatus asc]]], filters:[null])

could you please suggest me to resolve the issue.

    kishoren0003,

    Error Message you shared doesn't have enough information to debug. Check your Tomcat Server Log for more information and share here?

    A possible reason could be your data store entity is not published properly.
