Microsoft Fabric: [TooManyRequestsForCapacity] HTTP Response code 430: This Spark job can’t be run b

Hi TAnalytics   ,
Thanks for reaching out to the Microsoft Fabric Community forum. 

Please try the following troubleshooting steps:

• Check the Monitoring Hub for any active or queued Spark jobs. If there are jobs that are no longer needed, cancel them and retry the operation.
• Try restarting the Spark session (if one is active) or closing any open notebooks that may be consuming Spark resources.
• Wait 15–30 minutes and try again, as trial capacities can occasionally experience temporary resource contention or throttling.
• Create a new Lakehouse and attempt to load the same sample CSV there to determine whether the issue is specific to the Lakehouse or workspace.
• Verify that the workspace is correctly assigned to the Fabric trial capacity and that the trial is still active.
• Test with an alternative ingestion method, such as:
• Uploading the CSV directly to the Lakehouse Files section first and then creating a table from the file.
• Loading the file through a notebook using Spark.
• Try creating a new Fabric workspace attached to the trial capacity and repeat the test to rule out a workspace-specific issue.

I hope this information helps. Please do let us know if you have any further queries.
Thank you
