Query error - Inconsistent NCLOB data

Question

Hello,

I am trying to perform a query in an Oracle database and is returning an error

ORA-00932: inconsistent data types: expected - obtained NCLOB 00932. 00000 - "inconsistent datatypes: expected %s got %s" *Cause:
*Action:

The query is the following:

SELECT      DISTINCT SQL1.JOBNAME
        ,   SQL1.COMPILATION
        ,   SQL1.FOLDERPATH
        ,   SQL2.JOBSHORTDESCRIPTION
        ,   SQL2.JOBLONGDESCRIPTION
FROM        (
                SELECT      DISTINCT JOBNAME
                        ,   FOLDERPATH
                        ,   MAX(COMPILATIONTIMESTAMP) AS COMPILATION
                FROM        JOBEXEC
                WHERE       PROJECTNAME = 'MDM_PRD'
                        AND FOLDERPATH  NOT LIKE '%Temporario%'
                        AND JOBNAME     NOT LIKE '%Copy%'
                        AND JOBNAME     NOT LIKE '%Teste%'
                GROUP BY    JOBNAME
                        ,   FOLDERPATH
                        ,   COMPILATIONTIMESTAMP
            )       SQL1
INNER JOIN  JOBEXEC SQL2 ON SQL1.JOBNAME = SQL2.JOBNAME

This database records the information as JOBNAME receives a compilation, creating several records with the same name in the JOBNAME field, for this it is necessary to give a DISTINCT in JOBNAME to bring me only one record, but when the JOBSHORTDESCRIPTION and JOBLONGDESCRIPTION fields are within select, returns the error reported above.

I need to build this query by pulling all information without repetitions, but still with the description, someone would help me in how I can rebuild this query?
