Repeated AWS architecture diagram generation failures with internal error

I’m encountering repeated failures when trying to generate an AWS architecture diagram in Lucid.

The diagram request was attempted multiple times and failed each time with the message: "Something went wrong on our end." The issue occurred both with the original detailed prompt and with a condensed version, so it does not appear to be caused by prompt length alone.

Original prompt used: "An illustrative, clean vector-style AWS architecture diagram on a white background. At the top-left, a blue banner with a white cloud and "Region" text. Below it, a row of distinct, labeled service icons separated by dashed vertical lines: S3 bucket (green), DynamoDB (blue with lightning), SNS/SQS (red cloud), Route 53 (green tables), and a CodePipeline/CI/CD icon (purple brackets with code) within a shield lock. The entire center is a large green-outlined VPC. Within the VPC, two large blue-dashed boxes represent Availability Zones, both clearly labeled. At the top intersection, a central purple circular Internet Gateway icon. On the far-left, an S3 gateway endpoint shield and label. Inside each Public subnet: a green lock, a NAT gateway icon, and label. Inside each Private subnet: a blue lock, a server chip icon, and label. A central dashed box across the public subnets contains the Application Load Balancer icon and label. The servers in the private subnets are enclosed in a solid red-outlined rectangle labeled "Security group," and an orange cross icon for the Auto Scaling group is centrally positioned between the private subnets. All text is crisp and aligned."

Condensed prompt used: "Create a clean horizontal AWS architecture diagram on a white background. Add a blue Region banner at top left. Below it, show labeled AWS service icons separated by dashed vertical lines: S3, DynamoDB, SNS/SQS, Route 53, and CodePipeline/CI/CD. In the center, place a large green-outlined VPC containing two labeled blue-dashed Availability Zones. At the top center, add an Internet Gateway. On the left, add an S3 gateway endpoint. In each public subnet, place a NAT gateway with a green lock and label. In each private subnet, place server instances with a blue lock and label. Add an Application Load Balancer in a dashed box spanning the public subnets. Surround the private-subnet servers with a red Security group box. Place an Auto Scaling group icon centrally between the private subnets. Keep the layout crisp, aligned, and balanced."

Observed behavior:

  • Diagram generation failed repeatedly
  • Failure message was identical each time: "Something went wrong on our end"
  • Retrying with a simplified prompt did not resolve the issue

Please investigate whether this is a known issue with diagram generation, AWS icon rendering, or the generation service itself, and advise on any workaround or next steps.

@somnath.choudhuri another option you can try is uploading an example of what you want. 

If that doesn’t help, perhaps ​@alison cheney can help with this.
