Network Timeout Error in Unleash Client

[achraf-workspace]

Describe the bug

While initializing the feature flags using the unleash-client in our Node.js application, we occasionally encounter a FetchError: network timeout. The timeout error happens when attempting to register with the unleash server as shown by this URL: https://gitlab.com/api/v4/feature_flags/unleash//client/register

This error disrupts the normal initialization flow of our application's feature flag mechanism.

This error is thrown occasionally but not always. An investigation into possible networking issues, unleash server load or other possible causes would greatly help us to resolve the issue.

Steps to reproduce the bug

No response

Expected behavior

The expected behavior is that unleash-client should successfully register with the unleash server and initialize without throwing any network timeout errors.

Hi. Since you're using gitlab as your feature flag provider, we have no insight into their load or availability metrics. Reach out to Gitlab if you want help with seeing their availability

Hey, Is there any update on this issue? We encounter this issue when using the node unleash client

Hi @giladkoch that endpoint call client/register is a call that the SDK makes when you have metrics enabled and Gitlab does not support that protocol. So to get rid of that error you should disable metrics in Unleash SDK.
