In order to get the context I was trying to reproduce the issue locally and later planning to verify the fix. Here's some updates from my end.

• I was able to reproduce the same on local or on production without this fix
• I was trying to verify whether this fix solves the issue or not but unfortunately there's a new error occurs when I click on generate page

The problem that I mentioned earlier seems to be specific to my local env. Hence I am approving this PR.
