Error message

Failed to create portal root

What it means

For non-document tables the validator strictly rejects any data key that is not declared in table.schema — persisting undeclared fields would silently diverge from the persisted shape, and the adapters only store what the schema knows. Document tables (isDocumentTable) are exempt because they accept open shapes; regular tables fail with the offending key named.

Solutions

1. Add the field to the table schema if it should be persisted
2. Otherwise strip undeclared keys before the write: keep only Object.keys(table.schema)
3. If open shapes are intended, use a document table instead of a regular table

Example fix

// before
table.insert({ data: { id: 'a1', name: 'x', tempFlag: true } }); // tempFlag not in schema

// after
// option A: persist it -> add to schema: tempFlag: { type: 'boolean' }
// option B: strip before write:
const data = Object.fromEntries(
  Object.entries(entity).filter(([k]) => k in table.schema)
);
table.insert({ data });

function pickSchemaFields(data: Record<string, any>, schema: Record<string, unknown>) {
  return Object.fromEntries(Object.entries(data).filter(([key]) => key in schema));
}

table.insert({ data: pickSchemaFields(entity, table.schema) });

null

When it happens

Trigger: Inserting { id, name, tempFlag } when tempFlag was never added to the schema; renaming a field in code but not in the schema; computed/derived properties left on the object before insert; spreading a DTO (with transport-only fields) directly as entity data.

Common situations: Schema migration added the field to TypeScript types but not the table definition; reusing API DTOs as entities; newer client writing to an older schema.
