Error message

could not serialize result: object had neither a `ok` nor an `err` field

What it means

spacetime update install <version> accepts an --edition flag (comma-separated list, default "standalone"), but the installer currently implements only the standalone edition. The guard requires the parsed list to equal exactly ["standalone"]; anything else fails before any network I/O happens.

Solutions

1. Drop the --edition flag entirely; the default is standalone.
2. If you must pass it, pass exactly --edition standalone (single value, no extra list entries).
3. For hosted deployments, use the server/provider provisioning flow instead of the local installer.

Example fix

# before
spacetime update install 1.7.0 --edition cloud

# after
spacetime update install 1.7.0

When it happens

Trigger: Running spacetime update install 1.7.0 --edition cloud, --edition enterprise, or a multi-value like --edition standalone,cloud (value_delimiter=',' splits it into a list that no longer equals ["standalone"]).

Common situations: Assuming a cloud/enterprise edition can be installed locally with this CLI; scripts or docs carrying an edition flag; templates inserting the flag automatically.
