I am using html export feature for org files and I want to change the value of html-postamble (see [doc](https://orgmode.org/manual/HTML-preamble-and-postamble.html)).

Here is the `index.org` file:
```
#+title: Home

Welcome

#+options: html-postamble:"TESTSPACE"
```

When I export with `M-x org-html-export-as-html` everything is all right and I have the following at the end of the html produced buffer:

```html
<div id="postamble" class="status">
TESTSPACE
</div>
```

But if I add a space:
```
#+title: Home

Welcome

#+options: html-postamble:"TEST SPACE"
```

it raises this error I cannot solve:
`org-export--parse-option-keyword: End of file during parsing`
