2. Create some other node B that does literally anything else

4. No data 🐛
5. Connect node A to node C directly
6. Data

Hey @neverether,

That is an interesting one, it looks like the data is available but not until the node has input data. I have created N8N-7035 as our internal ticket to have a look at this.

I have a similar issue where data from a previous node isn't accessible. In my case, I'm processing an array of records in a batch:

Issue present after updating from 1.10.1 to v1.11.2 / Also present on v1.15.2 DB System: Postgres on Heroku using queue mode

Hey @sagararyal,

Your issue is very different and is likely to be related to paired items or the way the workflow has been created. Could you create a post on our support forum and include your workflow so we investigate further.
