Can you try and rexport the diagram with your dev tools open and try to find the payload that's being sent to the exportToDrawIo GraphQL query? You'll find it in the network tab. Make sure to have dev tools open early, the library used on the frontend does pre-fetching so it's possible to miss the call. When you get the payload, attach it here so I can debug.

Dear Stefano Please refer to the screenshot. I've also attached the HAR file. The export button is diabled. [cid:19d762c6-ba4a-481a-b46b-743557499a4d]

Having the exact same issue. Following.

Same issue on Safari and Chrome on MacOS. I can export a diagram with no filters, but once I remove too many resources, it starts throwing this error.

I'm also having this issue. Anyone knows if the export to diagrams.net had worked in any of the previous versions? The issue was reported not long ago I could assume the export has worked in older version. I haven't used this tool before just yesterday started and encountered this issue.

I have version: 2.0.2

I just deployed this solution into a fresh AWS account on Tuesday and am having the same issue when trying to export into JSON or draw.io compatible formats

[CarterSheehan]

I went down the path of trying to get more info printed out within the DrawIo lambda function when I had a idea that maybe something with the diagram itself was bad or not being sent to the function properly. So, I cleared the diagram and added a VPC resource and tried to export again, which worked. So, it feels like it could have something to do with the client-side request.
