Invalidate Redis Cache, but got a 500 error.

[JockChiang]

When we run curl http://localhost:3000/invalidate?tag=P1852,C20, we got 500 error with Invalid parameters for Clear cache request.
When we run yarn run cache clear, it is run normally.

We could not clear the Redis cache, this problem confused us.
Thanks.

It is not a bug of magento2-vsbridge-indexer. You got proper response from VSF-PWA - you did not provide key query string.
