Aborting because major version upgrade was not accepted.

Error message

Aborting because major version upgrade was not accepted.

What it means

Publishing a module built against SpacetimeDB 2.0 over a 1.0 database is a one-way major upgrade; the CLI demands the literal word 'upgrade' typed at the prompt. Any other input (empty line, 'yes', 'y', EOF) aborts the publish with this error and the database stays on 1.0.

Solutions

1. Read the linked upgrade notes (https://spacetimedb.com/docs/upgrade), then type 'upgrade' exactly
2. In automation, pre-accept by piping it: `echo upgrade | spacetime publish ...` or use the non-interactive skip flag for your flow
3. If not ready, pin your module to the 1.0 SDK/ABI and publish that instead

Example fix

# before
yes | spacetime publish mydb      # still aborts: must be the word 'upgrade'
# after
echo upgrade | spacetime publish mydb

if let Err(e) = publish_exec().await {
    if e.to_string().contains("major version upgrade was not accepted") {
        // keep the module on the 1.0 SDK or re-run with 'upgrade' piped in
    }
}

When it happens

Trigger: First publish after upgrading the SDK/CLI to 2.0 against an existing 1.0 database; typing 'yes' instead of 'upgrade'; CI pipes closing stdin so read_line returns EOF.

Common situations: SDK major-version bumps; automation hitting an interactive guard it cannot satisfy.
