Invalid Template Resource Exception

I try to build me first template following the steps from https://docs.typo3.org/m/typo3/tutorial-sitepackage but i can’t figure out what iam doing wrong.

I got this error on the frontend:
TYPO3Fluid\Fluid\View\Exception\InvalidTemplateResourceException

Tried resolving a template file for controller action “Standard->index” in format “.html”, but none of the paths contained the expected template file (). No paths configured.

Here are my configurations:

Page.typoscript:

Template Konfiguration für alle Domains

@import ‘EXT:fluid_styled_content/Configuration/TypoScript/setup.typoscript’

page {
// Header Data
headerData {
30 = TEXT
30.value (

        <link rel="preconnect" href="https://www.google-analytics.com" crossorigin>
        <link rel="dns-prefetch" href="https://www.google-analytics.com">
    )
}

// Fluid template section
10 = FLUIDTEMPLATE
10 {
    //
}

templateRootPaths {
    //
}
partialRootPaths {
    //
}
layoutRootPaths {
    //
}

// Hauptnavigation
dataProcessing {
    10 = TYPO3\CMS\Frontend\DataProcessing\MenuProcessor
    10 {
        special = list
        special.value = 7,2,3,11,4 // Auswahl von Navigationspunkten im Hauptmenü
        levels = 1
        includeSpacer = 1
        as = mainnavigation
    }
}

// Footernavigation
dataProcessing {
    20 = TYPO3\CMS\Frontend\DataProcessing\MenuProcessor
    20 {
        special = list
        special.value = 12,13,5,6 // Auswahl von Navigationspunkten im Footer
        levels = 1
        includeSpacer = 1
        as = footernavigation
    }
}

}

setup.typoscript:
@import ‘EXT:fluid_styled_content/Configuration/TypoScript/setup.typoscript’
@import ‘EXT:df_package/Configuration/TypoScript/Setup/*.typoscript’

page = PAGE

constants.typoscript:
@import ‘EXT:fluid_styled_content/Configuration/TypoScript/constants.typoscript’

page {
fluidtemplate {
layoutRootPath = EXT:df_package/Resources/Private/Layouts/Page/
partialRootPath = EXT:df_package/Resources/Private/Partials/Page/
templateRootPath = EXT:df_package/Resources/Private/Templates/Page/
}
}

Default.tsconfig:
mod.web_layout.BackendLayouts {
Default {
title = Default Layout
config {
backend_layout {
colCount = 1
rowCount = 2
rows {
1 {
columns {
1 {
name = Jumbotron
colPos = 1
}
}
}
2 {
columns {
1 {
name = Main Content
colPos = 0
}
}
}
}
}
}
}
}

On the screenshots you can see my file structure

Here is the static templated added on my backend
