Power Automate "Queue a new build" task results in TF400898 Exception

Hello,

I assume this is a known issue, but I failed to find any working solution in the internet.

My flow is being triggered by HTTP request (sent by an Azure DevOps pipeline), gets items from Sharepoint Online list view, puts them into variable and passes the variable to another pipeline (Queue a new build) which fails every time since yesterday's morning.

I've tried to run it with different users - all attempts have same effect since yesterday.
I've created another flow with same steps, with a new connection - no success has been reached.

Connector to Azure DevOps is out-of-the-box premium connector, nothing is on-prem, other flows work, queue a new builds in the same project and succeed.

Any suggestions are warmly welcomed.

Looks like that's happening because I'm trying to pass an Array as a pipeline parameter.
And YAML documentation states clearly that there's no such data type in "parameters" section.
The "object" type behaves the way I need, I just need to pass my array of values as an object from Power Automate Flow to Azure DevOps pipeline.
