Error when renaming an environment

Hi, everybody,
I am currently trying to rename an environment in Contenftul
As described in here:
https://www.contentful.com/developers/docs/references/content-management-api/#/reference/environments/environment/create-update-an-environment/console/js

This is my code:
const space = await client.getSpace(spaceId);
const backup = await space.getEnvironment(backupEnvironmentId);
backup.name = originalEnvironmentId;
await backup.update();

This is the error message I get. I don’t understand what is meant by “Source uuid translation missing”
{ SpaceEnvironmentPayloadInvalid: {
“status”: 400,
“statusText”: “Bad Request”,
“message”: “The environment change is invalid: Source uuid translation missing: en.errors.api_messages.unchangeable\nGiven input data: {“name”:“rollbackTest-new”,“validation_format”:“api”,“lock_version”:“3”}”,

},

},

}
at errorHandler (…\node_modules\contentful-management\dist\webpack:\contentfulManagement\error-handler.js:60:17)
at process._tickCallback (internal/process/next_tick.js:68:7)

Any idea what I’m doing wrong?

Best regards,
