Failed to create an update in Buffer

Hi everyone,

I've been trying for two days to get a pretty simple automation to work:

Trigger: a new row is added to a Google Sheet (which contains all the necessary information for a Buffer module).

When triggered, it should send the content to Buffer and post immediately on TikTok. However, I keep getting the error shown below. I'm using a direct download link from Google Drive (when I click the link, the file downloads automatically). The folder that contains the file is public. The file is a mp4 that usualy weights between 100 and 200 MB.

Any idea what might be going wrong?

Thanks in advance!

It works ! So the problem was indeed the file size. I guess the limit isn’t 100 MB as they mention. 

Just for the record, it worked with a file which sizes 18 MB.

 

Thank you very much for your time and help !

Hi ​@Killian 

Help links about using files in Zaps: https://help.zapier.com/hc/en-us/articles/8496288813453-Send-files-in-Zaps

See the limitations section.

Files larger than 100 MB may result in a time out error.

 

Try this…

Add a step to the Zap to get the File in GDrive by the File ID, which will return a file object for you to use.

Zap Action: GDrive - Retrieve a File or Folder by ID

Look for the file object, something like: File (exists but not shown)

Map that variable to the Buffer Video field.

NOTE: This still may not work due to the large file size, but worth a try.

Hi ​@Troy Tessalone, thanks for your reply. I read that Buffer only works using a downloadable link, which I am giving him.

The file that was supposed to be uploaded yesterday was actually 96,6 MB, the one that is supposed to be uploaded tonight is 80,3 MB :/

Any other idea ?

 

Thanks,

Killian

​@Killian 

You can try using another app such as CloudConvert to compress the file before uploading to Buffer.
