It looks like you commented out the line where you are setting your static accountId variable.  Line 2

Because this is a hard code id right, no need to hard code that id.then how we can solve this.

Hello,

In String accountId = PORTAL_ACCOUNT_ID;

you are assigning PORTAL_ACCOUNT_ID, but there is no value in PORTAL_ACCOUNT_ID. You can also check the same with debug statements.
