Data source binding not found.

Error message

Data source binding not found.

What it means

Flask NotFound (HTTP 404) raised at data_source.py:204 in DataSourceApi.patch (PATCH /data-source/integrates/<binding_id>/<action>). The lookup selects DataSourceOauthBinding by both id == binding_id AND tenant_id == current_tenant_id; if no row matches both, the binding 'does not exist' from this tenant's perspective and NotFound is raised before the enable/disable match runs.

Solutions

1. Re-fetch the integrations list via GET /data-source/integrates to obtain current binding ids for this tenant before patching.
2. Confirm the binding_id UUID is copied exactly (no extra characters) and belongs to the current tenant.
3. If the binding was deleted, re-authorize the data source to create a new binding and use the new id.
4. Ensure the request carries the correct tenant context header/session so current_tenant_id matches the binding's owner.

// Fetch current bindings for the tenant and confirm the id before patching.
const bindings = await fetch('/console/api/data-source/integrates').then(r => r.json());
if (!bindings.data.some(b => b.id === bindingId)) {
  throw new Error('binding_id not in this tenant');
}

function bindingBelongsToTenant(b: {id: string}, id: string): boolean { return b.id === id; }

try {
  await patchBinding(bindingId, action);
} catch (e) {
  if (e.status === 404 && /Data source binding not found/i.test(e.message)) { refreshBindings(); }
  else throw e;
}

When it happens

Trigger: PATCH /console/api/data-source/integrates/<binding_id>/enable|disable where binding_id does not exist, belongs to a different tenant, or was deleted. The tenant-scoped query returns None.

Common situations: Stale UI showing a binding that was removed; cross-tenant access attempt; UUID typo; or the binding was disabled+hard-deleted by another admin. Tenant scoping means another tenant's binding id is indistinguishable from a nonexistent one.
