Expected Behavior

I expect that annotations will be uploaded successfully and replace the existing annotations.

Possible Solution

I tried other formats such as CVAT 1.1 and it didn't work.

Context

We have existing annotations that we want to migrate to CVAT. We just bought the Team plan on Cloud but we cannot migrate our existing annotations using Datumaro 1.0 as we constantly face the error.

Environment

Operating system is Linux using Chrome on the latest version.
We are using CVAT hosted on Cloud (Team Plan).

I am having the same issue, did you solve this?

[vga-frontmatec]

Even though I get the error messages, the upload is still done successfully. I still don't know why that error happens, but it works on our ends anyway.
