Request.body should NOT have additional properties

Hi. Can you please help me solve the next problem? I built a workflow where I update another workflow with n8n API. Before the last n8n update it worked, but now I have next HTTP error: “message”: "400 - {“message”:“request.body should NOT have additional properties”}.
It doesn’t work even in n8n API playground.

Can’t share here the JSON that I’m using to update my workflow, it’s too big.

I found the reason. pinData JSON key needs to be removed for the workflow update


I just want to thank you @Nikolay_Titov , you help to save lots of minutes from my life.


You’re welcome!
