teamsApp/publishAppPackage fails with BadRequest for some localizations

[alexanderbob]

Describe the bug Running provisioning fails at the teamsApp/publishAppPackage stage with the following message:

Error: Unable to make API call to Developer Portal: Error, BadRequest, API name: publish-app, X-Correlation-ID: cc2f521b-b7f7-4cf2-adf1-ad5612c92192. This may be due to a temporary service error.

}

With trial and error, we narrowed this issue down to the length of localization properties.

For example, with manifest like the one below:

{
    "$schema": "https://developer.microsoft.com/json-schemas/teams/vDevPreview/MicrosoftTeams.schema.json",
    "manifestVersion": "devPreview",
    "version": "1.0.0",
    "id": "f12389cc-a4de-471e-a341-f413efc6f8cf",
    "packageName": "Microsoft.Dynamics.Sales.Productivity",
    "localizationInfo": {
        "defaultLanguageTag": "en-US",
        "additionalLanguages": [
            {
                "languageTag": "pl-PL",
                "file": "pl-PL.json"
            }
        ]
    },
    ...
}

And pl-PL.json file contents as the following:

{
    "$schema": "https://developer.microsoft.com/json-schemas/teams/vDevPreview/MicrosoftTeams.Localization.schema.json",
    "name.short": "Copilot dla działów sprzedaży",
    "name.full": "Copilot dla działów sprzedaży",
    "description.short": "Usługa...",
    "description.full": "...",
    ...
}

Provisioning fails with the error above.

Howver, shortening name.short string solves the issue:

{
    "$schema": "https://developer.microsoft.com/json-schemas/teams/vDevPreview/MicrosoftTeams.Localization.schema.json",
    "name.short": "dla działów sprzedaży",
    "name.full": "Copilot dla działów sprzedaży",
    "description.short": "Usługa...",
    "description.full": "...",
    ...
}

Schema file declares that max length for name.short is 30 characters:

However, all 3 strings for name.short property on lines 1-3 are causing provisioning to fail. Removing "Copilot" to shorten the string value (lines 6-8) solves the issue.

1. Copilot dla działów sprzedaży
2. Copilot pārdošanas nodaļām
3. Copilot dành cho Bán hàng

Looks like API endpoint incorrectly counts length for multi-symbol unicode characters, because all 3 are no longer than 30 characters, but caret position is at 33/31 symbol.

Based on the status code and API name in error message, this issue is duplicated with #10316. You can refer to it for more information.

I narrowed it down to the following locales:

1. lv-LV
2. vi-VN
3. pl-PL

Updated original post.

@alexanderbob Thank you for reporting the issue. We are currently working on resolving it.

As discussed in Teams, the API endpoint correctly counts the characters. We will improve the error message for localization files' json schema validation.
