Warning: Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('http://localhost:3000') does not match the recipient window's origin ('http://localhost:4006')

From time to time when you use global mini-app you will receive this error.

This is because your iframe document hasn't loaded yet when you call the postMessage() method.

condo/apps/condo/domains/miniapp/components/GlobalApps/GlobalAppsContainer.tsx

Lines 108 to 116 in 2fb65fc

	if (iframeOrigin && iframeWindow) {
	iframeWindow.postMessage({
	type: ORGANIZATION_CHANGE_MESSAGE_NAME,
	data: {
	// TODO(DOMA-5194): May be condoOrganizationId to be consistent with query-params?
	organizationId,
	},
	}, iframeOrigin)
