Cannot extract accessor name from query

Error message

Cannot extract accessor name from query

What it means

When spacetimedb-update's CLI proxy runs from a cargo target/ directory (a dev checkout), it proxies to the spacetimedb-cli binary cargo should have built into the same artifact directory (target/<profile>/spacetimedb-cli), instead of the installed current version. If that binary is absent, it bails with explicit build instructions.

Solutions

1. Build the CLI into the same profile: cargo build -p spacetimedb-cli (add --release if you run the release updater).
2. Or run the installed updater outside target/ so it resolves the CLI via the current version directory instead.
3. If you meant to run the repo CLI, prefer cargo run -p spacetimedb-cli -- <args>.

Example fix

# before
$ ./target/debug/spacetimedb-update --version
error: ... spacetimedb-cli binary doesn't exist ...

# after
$ cargo build -p spacetimedb-cli
$ ./target/debug/spacetimedb-update --version

# Ensure the CLI exists in the same profile as the updater you run:
PROFILE=debug   # or release
test -x "target/$PROFILE/spacetimedb-cli" \
  || cargo build -p spacetimedb-cli $([ "$PROFILE" = release ] && echo --release)

When it happens

Trigger: Executing target/debug/spacetimedb-update (or target/release/...) in the SpacetimeDB repo when spacetimedb-cli has not been built into the same profile directory — e.g. after only building the update crate, or after cargo clean.

Common situations: cargo build -p spacetimedb-update only; cargo clean between builds; copying the updater binary out of a partial build tree and running it from target/.
