504 Error on Create Board From Template

I am submitting the following query to create a new board from a template to the GraphQL v2 api and I receive a timeout (504 Gateway Error), however the board still gets created in the UI.

{"query": "mutation { create_board (board_name: \\"Shift Archive - February\\", workspace_id: ******* board_kind: public, template_id : 3812705305) { id }}"}

The template contains no items, 1 group and ~15 cols (some linked). Any explanation or solution would be appreciated.

Additionally: Running the same query in playground I get:

TypeError: Failed to fetch

Edit: I require a response to continue with the workflow.

Hello there @Ben1,

I don’t see in the text you sent any error messages from our server.

What is the exact response you get from our server?
