Bug in convert_mimetype_of_file_on_google_drive: ReferenceError: blob is not defined #11
Description
Hello,
There appears to be a bug in the convert_mimetype_of_file_on_google_drive tool function.
Error:
When calling the tool with a valid file ID for a Google Slides presentation and dstMimeType: 'application/pdf', it fails with the following error:
ReferenceError: blob is not defined at management_drive.js:267:128
Code Analysis:
The issue seems to be in the management_drive.js file within the convert_mimetype_of_file_on_google_drive function.
The current implementation appears to be:
const file = DriveApp.getFileById(id);
const blob = file.getAs(dstMimeType);
const newFile = DriveApp.createFile(blob.setName(file.getName()));Suggested Fix:
A more robust implementation, which should prevent this error, is to explicitly get the file's blob before converting its type. The line should be changed as follows:
From:
const blob = file.getAs(dstMimeType);To:
const blob = file.getBlob().getAs(dstMimeType);This change ensures a valid blob is retrieved before the conversion is attempted and should resolve the issue.
Thank you for maintaining this useful toolset.

Thank you for your comment.
Unfortunately, I cannot find the following part from management_drive.js.
Also, from your showing error message
ReferenceError: blob is not defined at management_drive.js:267:128, I confirmed the reason for the error. It's as follows.From

I will modify it at the next official update soon. So, as the current update, I have modified it as the developer mode of the library.
Thank you for reporting it.
