feat(better-error-handling): Added a method to check al the required sub-blocks of the workflow blocks.

[mo-amir-code]

Description

Added a method to validate all the required sub-block values of each block of current workflow.

Please include a summary of the change and which issue is fixed. Please also include relevant motivation and context:

I added a method to check all the required sub-blocks values of workflow blocks. If any required field is missing then it is showing error alert/notification message only for first detected unfilled required sub-block value. For example: user created a workflow with 4 blocks and missed 2 required sub-block values in two different block then that method will show alert message for first unfilled sub-block value because it is checking flow wise and if user filled that required sub-block value and then the method will give an error message again to another unfilled sub-block value.

Fixes #340

PR Summary

This PR adds validation for required sub-block values in workflow blocks, improving error handling by providing specific error messages for missing required fields before execution begins.

• Added handleCheckRequiredFieldsOfAllBlocks method in /apps/sim/app/w/[id]/hooks/use-workflow-execution.ts to validate required inputs
• Method checks blocks sequentially and shows error notification for first missing required field
• Integrated validation into workflow execution flow through handleRunWorkflow
• Provides user-friendly error messages like "API key is required for block X" instead of generic errors
• Addresses issue #340 by improving error visibility and debugging experience

@mo-amir-code the use workflow execution doesn't only run in the UI, but on the API, webhook, and chat message. How can we return a value so that an error is displayed for those?

[mo-amir-code]

@emir-karabeg I was thinking only in UI, I will start working on it

[emir-karabeg]

@mo-amir-code any updates? :D

@emir-karabeg
I wanted to let you know that I’m currently unable to continue working on the PR due to my ongoing college exams. As the exams are still in progress, I won’t be able to contribute further at the moment.

Please feel free to reassign or let someone else take over the task if needed. I really appreciate the opportunity to contribute and hope to be more active once my exams are over.

Thanks for your understanding.

[emir-karabeg]

@mo-amir-code no problem! Best of luck with your exams and looking forward to hearing from you soon! Let us know if we can help in any way :D @waleedlatif1 and I studied CS at Berkeley
