Have you configured your activity's security tab like below? if not can you configure as below and check again?

'Require authentication to run' should be unchecked and check 'allow direct invocation....'

Hi PrasenjitK,

If the issue is not getting resolved after making the above changes means, please create an SR in my support portal.

We are unable to open the URL as per the screenshot.
So we are unable to do this type of changes.
please suggest if there has any alternative way to solve this.
Or can we make any changes for the database?

Hi You shouldnt check "Requires authentication to run" in your activity's security tab.

Please check once.
