readPlaceAsset() fails on Github Actions and ends all logged in session.

[Stayroh]

My goal is to save the terrain from on place as an .rbxmx file. To get the place file I use readPlaceAsset(), because I have Team Create enabled. To use this feature on Github Actions I have created an alt account, which I gave permission to the place. I logged into Roblox with that account in Google Chrome on my Personal Computer and saved the security cookie. When ever I try to run remodel run RemodelTest.lua --auth "<the cookie>" it perfectly works and it saves the terrain as "Terrain.rbxmx". Here is the remodel code:
local TerrainPlace = remodel.readPlaceAsset("9870598446") local Terrain = TerrainPlace:GetService("Workspace").Terrain remodel.writeModelFile("tempAssets/Terrain.rbxmx", Terrain)
But when ever I try to use this in Github Actions (the cookie saved as a Github secret) it fails with this error:
Error: [ERROR] callback error stack traceback: [C]: in field 'readPlaceAsset' [string "RemodelTest.lua"]:1: in main chunk caused by: Unknown response trying to read model asset ID 9870598446. Response is: Ok("{\"errors\":[{\"code\":0,\"message\":\"User is not authorized to access Asset.\"}]}") Error: Process completed with exit code 1.
And it even logs me out of my Google Chrome session.
This is the line in my Github workflows:
- run: remodel run RemodelTest.lua --auth "${{ secrets.PLACELOADER_1_COOKIE }}"

Any ideas to solve this issue?
