I am trying to restore my elasticsearch on a new machine.
I copied the backup across, set up a new repo with the same name (called myrep). I have check if this works by doing:
```
> `GET http://127.0.0.1:9200/_snapshot`
```
which returned:
> {
> "myrep": {
> "type": "fs",
> "settings": {
> "compress": "true",
> "location": "myrep"
> }
> }
> }
When I try to do a restore doing:
> POST [http://127.0.0.1:9200/\_snapshot/myrep/snapshot\_1/\_restore](http://127.0.0.1:9200/_snapshot/myrep/snapshot_1/_restore)
I get an error:
> {
> "error": {
> "root\_cause": [
> {
> "type": "illegal\_argument\_exception",
> "reason": "Unknown parameter type"
> }
> ],
> "type": "illegal\_argument\_exception",
> "reason": "Unknown parameter type"
> },
> "status": 400
> }
Can anyone help?

Please don't post images of text as they are hardly readable and not searchable.
Instead paste the text and format it with `` icon. Check the preview window.

Mistake on my behalf. I had a body in my post request which was causing issues.
