az webapp deploy fails with just "Bad Request" (using `--src-url`)

### Describe the bug

When running the `az webapp deploy` command below, all I get is a "Bad Request" response. Pretty hard to debug that…

### Related command

`az webapp deploy --resource-group ACME-Dev-RG --name acmecom-dev --type zip --src-url 'https://acmecom.blob.core.windows.net/artifacts/release.zip?__SAS__'`

(Tried with an explicit `--async true` as well, to avoid any side effects of https://github.com/Azure/azure-cli/issues/27506)

### Errors

```
Initiating deployment
Deploying from URL: https://acmecom.blob.core.windows.net/artifacts/release.zip?__SAS__
Bad Request
```

### Issue script & Debug output

This has been redacted and shortened a bit (removed the successful informaton retrieval about the webapp, for example).

I hope the relevant bits are all there.

There seems to be no response body whatsoever, so all I have is `400 Bad request`
