Great! How could I missed that? Thank you very much.

Thank you for your comment. Unfortunately, I couldn't understand about your situation from your comment. I apologize for this situation. So can you provide the detail information (flow and script) for completely replicating your situation? If there are some bugs, I would like to modify them.

Hello. Here is the code I tried to use the function main

function main() {
  var id = 'abcd';
  var fileBlob = DriveApp.getFileById(id).getBlob();
  
  var metadata = {
    name: "OCR-PDF-" + (new Date()).getYear(),
    mimeType: MimeType.GOOGLE_DOCS
  };
  
  var form = FetchApp.createFormData();
  form.append("metadata", Utilities.newBlob(JSON.stringify(metadata)));
  form.append("file", fileBlob);
  var url = "https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart";
  
  var params = {
    method: "POST",
    headers: { Authorization: "Bearer " + ScriptApp.getOAuthToken() },
    body: form
    // muteHttpExceptions: true
  };
  
  var res = FetchApp.fetch(url, params);
  Logger.log(res);
}

And I got an exact error in slovak language:

Požiadavka zlyhala, pretože služba https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart vrátila kód 400. Skrátená odpoveď servera: { "error": { "errors": [ { "domain": "global", "reason": "parseError", "message": "Parse Error" } ], "code": 400, "messa... (ak chcete preskúmať celú odpoveď, použite možnosť muteHttpExceptions) (riadok 69, súbor Code, projekt FetchApp)

Translated: Request failed, because service https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart response code was 400. Response from server: { "error": { "errors": [ { "domain": "global", "reason": "parseError", "message": "Parse Error" } ], "code": 400, "messa...
line 69, file Code, project FetchAppp

I do not know how to debug code of FetchApp from a library, or how can I just copy the code to my project.

Thank you

Thank you for replying. From your replying, I think that I could correctly understand your situation.

Modification point:

• For metadata, please add the mimeType of application/json.

So could you please modify as follows and try to run again?

Modified script:

From:

form.append("metadata", Utilities.newBlob(JSON.stringify(metadata)));

To:

form.append("metadata", Utilities.newBlob(JSON.stringify(metadata), "application/json"));

If this was not the solution, I apologize.
