Question: How can errors be surfaced when using Classic Universal Login?
Answer:
When it comes to working with Classic Universal Login we show errors in separate sections. For example:
• An invalid password error for a database connection is shown on the Universal login page itself.
• Certain invalid requests or invalid browser states can lead to an error page being shown
• Whereas other conditions like a blocked user result in an error response being delivered to the client application
Note: flashmessage can be leveraged when you have Lock implemented to quickly show general type( success, error) messages, but its use within Universal Login may not be possible depending on the exact error scenario.
