Missing type name for

Error message

Missing type name for ${typeBuilder.constructor.name ?? 'TypeBuilder'} ${JSON.stringify(typeBuilder)}

What it means

spacetime publish accepts a parent database either via --parent <parent> or inline in the database name as <parent>/<child>. validate_name_and_parent splits the name on '/'; when both forms are supplied they must designate the same parent, otherwise the request is ambiguous and rejected. (Equal values are allowed and deduplicated; the parent must also be a valid domain or identity.)

Solutions

1. Drop --parent and keep only the path form: spacetime publish myorg/mydb.
2. Or keep --parent myorg and pass only the child name: spacetime publish --parent myorg mydb.
3. If both must appear (e.g. templated commands), make them identical — the duplicate is accepted.

Example fix

# before
spacetime publish --parent alice myorg/mydb

# after
spacetime publish myorg/mydb
# or
spacetime publish --parent myorg mydb

if [[ "$DB_NAME" == */* && -n "$PARENT" && "$PARENT" != "${DB_NAME%%/*}" ]]; then
  echo "conflicting parent: --parent $PARENT vs $DB_NAME"; exit 1
fi

When it happens

Trigger: spacetime publish --parent alice myorg/mydb where myorg != alice. Also fires for any invocation with a slash-containing name plus a --parent value that differs from the path's first segment.

Common situations: Shell history reuse (--parent left over plus an edited name); wrapper scripts that always set --parent while the user types a path-style name; muscle memory from tools where both are accepted independently.
