Dynamic SQL Query To Temp Table In SSIS - sql-server

Question

I am attempting to create a global temp table based off of a dynamic SQL query. I am using an execute SQL task. Thus far, whenever I execute it, the temp table is not created. Below is my script. I have altered my connection property so that it retains the connection and I set the delay validation to true in the data flow task. When I query for the global temp table, the object doesn't exist.
drop table if exists ##HOCExp
DECLARE #columns NVARCHAR(MAX), #sql NVARCHAR(MAX);
SET #columns = N'';
SELECT #columns += N', p.' + QUOTENAME(ShortLabel)
FROM (SELECT p.ShortLabel FROM dbo.TECHEnumValue AS p
JOIN dbo.CNTHospitalOrClinicExposure AS o
ON p.EnumValue = o.MPLEntityExposureBasis
where p.MyEnumType_ID = 610 and p.ShortLabel <>''
GROUP BY p.ShortLabel) AS x;
SET #sql = N'
SELECT EntityFK, ' + STUFF(#columns, 1, 2, '') + '
into ##HOCExp
FROM
(
SELECT p.ShortLabel
, o.MPLEntityExposureUnit
, concat(o.MyInsuredItemHospitalOrClinic_ClassID
, o.MyInsuredItemHospitalOrClinic_ID) as EntityFK
FROM dbo.TECHEnumValue AS p
INNER JOIN dbo.CNTHospitalOrClinicExposure AS o ON p.EnumValue = o.MPLEntityExposureBasis
where p.EnumValue <>0 and p.MyEnumType_ID = 610 and o.MyInsuredItemHospitalOrClinic_ID <>0
) AS j
PIVOT
(
SUM(MPLEntityExposureUnit) FOR ShortLabel IN ('
+ STUFF(REPLACE(#columns, ', p.[', ',['), 1, 1, '')
+ ')
) AS p;';
--PRINT #sql;
EXEC sp_executesql #sql;
select * from ##HOCExp
