In block_submit.js I have added Validation for 'someVariable', So that a null value is not passes in the condition

[ravichandra1998g]

Hello @rashmi269

On Submit validations are usually done on fields that are mandatory before submitting.

So the field mandatory validation can be done by making the field/variable mandatory without the code.

Thank you for your efforts!
