@Marvin My team has been using Prefect Cloud for a couple of years, but recently a specific flow we run started hitting a 429 error

ERROR Crash detected! Execution was interrupted by an unexpected exception: PrefectHTTPStatusError: Client error '429 Too Many Requests' for url 'https://api.prefect.cloud/api/accounts/10c0fe8b-8eff-4c6c-9e25-86073f767cc2/workspaces/535a248a-8f77-465a-98ee-90b3f52535ef/task_runs/efcb7909-2c03-416b-9e38-a1928e8a3331/set_state' Response: {'detail': 'Orchestration API rate limit reached. To raise your rate limit please contact help@prefect.io'} For more information check: https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/429

It looks like you've hit the rate limit for the Orchestration API in Prefect Cloud. Here's a step-by-step approach to address this issue: 1. Understand the Rate Limits: - The

429 Too Many Requests

error indicates that the API calls to Prefect Cloud are coming in too quickly, exceeding the allowed rate limit. 2. Identify the Source: - Identify which part of your flow or operations might be generating excessive API calls. 3. Rate Limiting Strategies: - Implement strategies like exponential backoff, throttling, or batching requests to ensure that your flow does not hit the rate limit again. 4. Contact Prefect Support: - Since the error message suggests contacting Prefect for a higher rate limit, you should reach out to help@prefect.io to discuss increasing your rate limit. 5. Documentation and Community Resources: - Refer to the official documentation and community resources for more details on rate limits and best practices. Let's search the Prefect documentation and GitHub issues for more information on handling this error. It seems your issue is related to exceeding the rate limits enforced by Prefect Cloud. Here are some key points to consider: 1. Current Rate Limits: - Personal Accounts: 400 requests per minute. - Pro Accounts: 2,000 requests per minute. - When these limits are surpassed, a

429 Too Many Requests

error is returned alongside a

Retry-After

header indicating when it's safe to retry. 2. Handling Rate Limits: - Implement retry logic with exponential backoff in your API calls to handle temporary rate limit breaches. - Optimize the frequency and number of API calls to stay within the allowed limits. 3. Increasing Limits: - Contact Prefect support at help@prefect.io to discuss increasing your rate limits if your operational needs justify it. 4. Documentation and Resources: - Prefect API Rate Limits & Retention Periods - GitHub Issue on 429 Error - GitHub Issue on Docker Pull Rate Limit By revisiting your flow's structure and reach out to Prefect support for increased limits if necessary, you can optimize your operations to stay within prescribed limits. If further customization is required, refer to Prefect's Comprehensive Documentation for additional techniques in handling API rate limitations effectively.
