I am trying to update the chart dynamically that is embedded in a Google Slides, but it throws an error at me.

This is the function that I came up with to replace some specific text that is placed in my base Google slide.

 public function getGoogleDrivePdf($fileId, $substitutions)
{
    $client = $this->getGoogleClient();
    $driveService = new Google_Service_Drive($client);
    $slidesService = new Google_Service_Slides($client);
    $copy = new Google_Service_Drive_DriveFile([
        'name' => $substitutions['student_name'] . ' presentation',
    ]);
    $driveResponse = $driveService->files->copy($fileId, $copy);
    $slideFileId = $driveResponse->id;
    $requests = [];
    foreach ($substitutions as $key => $value) {
        $requests[] = new Google_Service_Slides_Request(
            [
                'replaceAllText' => [
                    'containsText' => [
                        'text' => '{{'.$key.'}}',
                        'matchCase' => true
                    ],
                    'replaceText' => $value
                ]
            ]
        );
    }
    $batchUpdateRequest = new Google_Service_Slides_BatchUpdatePresentationRequest([
        'requests' => $requests,
    ]);
    $updateResponse = $slidesService->presentations->batchUpdate($slideFileId, $batchUpdateRequest);
    $response = $driveService->files->export(
        $slideFileId,
        'application/pdf',
        [
            'alt' => 'media',
        ]
    );

    $content = $response->getBody()->getContents();
    $driveService->files->delete($slideFileId);
    // Download
    $response = new Response();
    $response->headers->set('Content-Type', 'application/pdf');
    $response->headers->set('Content-Disposition', 'attachment; filename="' . $substitutions['slide_filename'] . '"');
    $response->setContent($content);

    return $response;
}

This function replaces the text I want that are in the Google Slide and downloads the slide as a PDF file without an issue.

But, now I want to add a chart to the slide and change the chart values dynamically. I tried to accomplish this by changing the values in source Google Sheet to replaceable text but It throws me this error.

{
“error”: {
“code”: 400,
“message”: “Invalid value at ‘requests[9].replace_all_text.replace_text’ (TYPE_STRING), 10nInvalid value at ‘requests[10].replace_all_text.replace_text’ (TYPE_STRING), 20nInvalid value at ‘requests[11].replace_all_text.replace_text’ (TYPE_STRING), 30nInvalid value at ‘requests[12].replace_all_text.replace_text’ (TYPE_STRING), 40nInvalid value at ‘requests[13].replace_all_text.replace_text’ (TYPE_STRING), 50nInvalid value at ‘requests[14].replace_all_text.replace_text’ (TYPE_STRING), 50nInvalid value at ‘requests[15].replace_all_text.replace_text’ (TYPE_STRING), 50nInvalid value at ‘requests[16].replace_all_text.replace_text’ (TYPE_STRING), 50”,

Any idea how to fix this or any workarounds?
