makeFindRelationship: interpolatedQuery targets not supporte

Error message

makeFindRelationship: interpolatedQuery targets not supported

What it means

findRelationship walks schema targets to locate a relationship by name; when it encounters a target of type 'interpolated' it throws, because interpolated query targets are not supported by this reference implementation.

Solutions

1. Remove or replace interpolated targets in the schema with table or query targets.
2. Use a connector backend that implements interpolated query targets if you need them.
3. Avoid query features (nested order_by / exists on related tables) that force relationship resolution over interpolated targets.

const hasInterpolated = Object.values(schema.targets ?? {}).some((t: any) => t.type === 'interpolated');
if (hasInterpolated) throw new Error('schema uses unsupported interpolated targets');

When it happens

Trigger: Any query (exists expressions, order-by paths, etc.) that triggers findRelationship on a schema whose targets include { type: 'interpolated', ... } entries while resolving a relationship name.

Common situations: Using schemas authored for connectors with interpolated-query support against this reference agent; advanced NDC schemas using argument interpolation that the reference backend hasn't implemented.
