When a task fails, you have access to error details in Tasq, in the task details page.
In the JSON tab, the code of the error is available, with a more detailed message and sometimes tips to solve the error. In the above example, one can read:
{
"errors": [
{
"code": "0ZTNT4SA",
"message": "Resource download failed: Error while trying to get the manifest: Can't find Docker image registry-1.docker.io/huanjason/scikit-learn:20.04. Make sure the Docker image exists in this registry, and that you provided proper credentials",
"debug": null }
]
}
In this error message, we see that the docker image couldn't be found in the docker hub registry, probably because of a typo in the docker image or its tag.
