[Patch] BUG: Metadata API Request Error Handling / https://github.com/alephdata/aleph/issues/3812 /

[dimitardanailov]

I'd like to share my proposal about the following issue: https://github.com/alephdata/aleph/issues/3812

The patch uses two different protection techniques.

#1 state. metadataRequestAttempts tracks how many attempts are requested to axios REST API layer. The current restrictions to const MAX_METADATA_REQUEST_ATTEMPTS = 5;

#2 executeRetryPattern uses setTimeout. setTimeout is going to be increased each time if the request has any error.

Accomplishments

#1 The previous version executed many request without any delay between requests.

#2 The gap between UI pop dialog is increased from a few ms to 2000+ ms.

Why the current pull request has a draft status ?

The main reason for that is: I've been working on different task. I've a plan to restructure the source code to add a state machine and code splitting between Happy and Unhappy path.
