When I try to ship a flow I get this error. But when I test I do not see error.
Flow error:
Cannot read properties of undefined (reading 'length')

I tried removing the only one code block where I use length, but still find same erroor.

The error message "Cannot read properties of undefined (reading 'length')" typically appears when you're attempting to access the 'length' property of something that is undefined. Here are a few steps to help you troubleshoot this:
1. Check Variable Initialization: Ensure that the variable you are trying to access with
.length is properly initialized and is indeed an array or string. If it's possible that it could be undefined, add checks in your logic to handle such cases.
2. Input Validation: Before you use .length, add a check to ensure that the variable is not undefined. For example:
3. Trace the Source: Go back to where the variable is being set or assigned. Confirm that this variable is getting a value correctly before it's used.
4. Mock Data/Test Cases: If you have test cases or mock data, verify that they align with the expected data structure in your workflow.
5. Review Node Dependencies: Sometimes the issue might be related to a previous node's output that is supposed to feed into the length operation. Verify those nodes are correctly configured and returning expected outputs.
Since you've already removed the code block where you used .length, it might be another place in your code or workflow where a similar logic needs to be addressed.

Hi @abhinesh we are working on fixing this issue, for now you can submit your workflow via in-app support for this.
ok now this is working @Gaurav Chadha But I have another challenge. A wait function node is consuming so much credits. I need to add 1-2 minute delay in my workflow because some lengthy AI bot replies will look more natural that way. but since that is consuming credits, I cannot use the wait node.
