stopword settingsUpdate FST error

[Magorx15]

Describe the bug
When i set the stopwords of an index with certain stopwords it gives an internal FST error.
Examples that work:

{
    "stopWords":
    [
        "akkor"
    ]
}

{
    "stopWords":
    [
        "akár"
    ]
}

Doesn't work:

{
    "stopWords":
    [
        "akkor",
        "akár"
    ]
}

The error that i am getting:

"error": {
    "message": "internal: FST error.",
    "code": "internal",
    "type": "internal",
    "link": "https://docs.meilisearch.com/errors#internal"
}
