I am having the same exact error. I am building a powershell script to automate publishing. I have enabled Fiddler and I can catch the 400 bad request, but when I repeat, the same exact request via fiddler...it works. Is there indeed a timing thing? I am doing a few API calls, pretty much back to back. I am getting an AAD token, followed by getting the groupid, then the reportid based on the name of the pbix file, to make sure the workspace and report exist and if so, need to be overwritten. I then publish the pbix, followed by taking ownership of the dataset and setting parameters. I then am trying to bind the dataset to a gateway using:
https://api.powerbi.com/v1.0/myorg/groups/GroupId/datasets/DatasetId/BindToGateway
To it I use the following body:
{"gatewayObjectId": "GatewayId"}
First attempt as part of the script I get a:
HTTP/1.1 400 Bad Request

But using Fiddler's Composer I clone the same EXACT request and get:

Please help. I am actually setting up an Azure DevOps Release pipeline to automate this process for my developers.
Update:
I have noticed that a 2 second sleep seems to help, but now I am getting this on the update parameters request:

I think it is self explanatory.
