Step 1: Sign in. You will get a TOEKN in response if email and password are correct.

requests.post(
    "http://{}/api/auth/signin".format(SERVER_URL),
    json={
        "email": USERNAME,
        "password": PASSWORD,
    }
)

Step 2: Put the TOKEN in the API request headers.

requests.post(
    "{}/api/user/code".format(SERVER_URL),
    headers = {
        "X-Token": TOKEN,
        "X-Username": TOKEN,
    },
    json={
        "modules": CODE_TEXT,
        "branch": BRANCH_NAME,
    },
)

Here is a list about all API I could found (written in Python). Most of them are tested. https://github.com/Qionglu735/screeps_tool/blob/master/screeps_api.py#L185

got the exact same issue here, after rebooting vm machine and restarting private server.

spawn.store and spawn.storeCapacityResource become an empty object.

if put energy into the spawn, spawn.store["energy"] will reappear, but spawn.storeCapacityResource still empty.
