hi every one, i have the next code:    function saveFile(fileField) {
				
        var fileObj = file.create({
            name: fileField.name,
            fileType: fileField.fileType,
            contents: fileField.getContents(),
            folder: 4165 
        });
				
        var fileId = fileObj.save();		
        return fileId;
    }

[19:20] and i need use it to upload a public_key.pem file but it is showing this error: Error: {"type":"error.SuiteScriptError","name":"SSS_INVALID_TYPE_ARG","message":"You have entered an invalid type argument: MISCBINARY","id":"","stack":["Error\n at saveFile (/SuiteScripts/0004 - Card/SD_SL_UploadPemFile.js8728)\n at Object.principalFunction (/SuiteScripts/0004 - Card /SD_SL_UploadPemFile.js3634)"],"cause":{"type":"internal error","code":"SSS_INVALID_TYPE_ARG","details":"You have entered an invalid type argument: MISCBINARY","userEvent":null,"stackTrace":["Error\n at saveFile (/SuiteScripts/0004 - Card /SD_SL_UploadPemFile.js8728)\n at Object.principalFunction (/SuiteScripts/0004 - Card /SD_SL_UploadPemFile.js3634)"],"notifyOff":false},"notifyOff":false,"userFacing":true} [19:20] but when i save a .txt file it works fine, do you know what is the error? thanks!!

what happens if you change the filetype to PLAINTEXT?

you haven't really shared enough code, but the guess is that fileField is actually a file.File
