Problems with SplitInBatches and HTTP requests

[liushengyi]

I want to use the node for SplitInBatches to post Http requests like this.

I set the expression from input.

when I set Batch size equals 1 . it’s work。
but，when i set batch size lagger than 1 .it does not work .there is only first one of every batch is right.
How would I get this working?

Sounds like the same problem as described here:

How many items does the Track-Node contain? Because if it only contains one that would cause an issue like this. In this case the node would execute 12 times, once for every item. For each of them it would look for the correct item on both in the expression referenced nodes. For Playlist it would find data for all 12. For Track it would then only find data for the first one. For it to work you have to tell n8n to always use the data of the first item (the item with index 0) which you can do by…

In this case, is the problem that they are in different “runs”. The Set-Node did execute only once. The other nodes multiple times. So you have to then additionally also define the run index 0 like this to say specifically that you want the data of the first item of the first run:

{{ $item(0, 0).$node["Set"].json["token"] }}

You can find the documentation here:
