OData: Request failed: The remote server returned an error: (429).

Hi AnkitKukreja ,

When a user exceeds usage limits, SharePoint Online throttles any further requests from that user account for a short period. All user actions are throttled while the throttle is in effect.

I found two similar threads during my investigation where some accepted solutions were mentioned, hope it helps you.

Solved - OData: Request failed: The remote server returned an error: (429). (429 TOO MANY REQUESTS) 

Solved - datasource.error: sharepoint: request failed: the remote server returned an error: (429)
