I don’t know if anything like this already exists, but I am looking for a different way to pass data variables than referring to a previous node in the expression. This is for 3 reasons… I find the current method insanely buggy. So often the data is showing in the input, but when I drag the schema…

It looks like your topic is missing some important information. Could you provide the following if applicable. n8n version: Database (default: SQLite): n8n EXECUTIONS_PROCESS setting (default: own, main): Running n8n via (Docker, npm, n8n cloud, desktop app): Operating system:

@YodAI , the problem you experience can be explained by your expression relying on auto-determination of the paired items (via .item.). This could fail when the workflow includes IF nodes, switches, and custom nodes. That is when one-to-one relationship is deviated. You can refer to the explanation…

Thanks @ihortom - I think I get what you are saying. It seems a bit of a usability issue then that it does not just auto-populate with the optimal expression when you drag the variable into the expression field. However, I don’t see how this fixes the issue with the sub-workflows. It would be far mo…

it still feels very much like both a bug (as in that the item is defined, in this example ‘var’, and it is the expression that n8n created when dragging the variable into the field, and a usability issue - I should not need to go through the docs to find ways to hack it and make it work. my feeling …

@ihortom - thanks again for a detailed breakdown. However, I would say, having built multiple SAAS companies and web app projects, it is a bug when something does not insert a functioning expression. It may not be a bug in terms of how it has been coded, but it is generating incorrect code within th…

Hey @YodAI , thank you for your detailed feedback. We really appreciate it. Your insights are valuable, and I will share them internally. As for sharing the data between sub-workflows it is achieved in such a way that the data of interest would have to be passed on to Execute Workflow node. You can…

@ihortom - the issue I have with sub workflows, is that it is when running them on multiple items. When you want to run a block of multiple items, each with multiple objects, in a uniform way, then the addition of the extra field breaks the formatting. They way you are suggesting works in many use c…

[image] YodAI: Is there no way to reference a session ID across a single sequence (made of both master and sub flows)? If so, this would also fix the issue, as I could then use an external database as has been suggested. I’m afraid not. Each (sub-)workflow runs in its own space. You can only …

I’m afraid not. Each (sub-)workflow runs in its own space. You can only pass the data between them explicitly as it was already discussed.
