Could you please tell me what may be the reason why the preview just keeps running and what should I do to make it work?

In case of my pipeline, it is sometimes working, it sometimes keeps running without providing results. (It is working around 1 out of 10 times...)

The data source is an API, I used the HTTP client stage with basic Authentication. I added the credentials to the credential page. It is a JSON array of Object, the setting was modified at the HTTP client stage.

We have only 7 fields...

Is there any setting that I should modify?

How long does the first successful request take? If it's longer than the configured max preview timeout, you won't see any data. Did you try increasing the preview timeout?

When I receive data, it appears in a second. When I do not receive, I do not receive a timeout message, it just keeps running. After some investigation, we think that it may be related to a cache? (if we disable cache, we always receive data)

we need to continue our investigation, but if you have any idea that could help us, it would be much appreciated.
