Hello!
I’m trying to add an attachment to a specific task but I’m getting this error:
{
“errors”: [
{
“message”: “file: File is not an object”,
“help”: “For more information on API status codes and how to handle them, read the docs on errors: Build an app with Asana”
}
]
}
Please advise, thanks!
Are you giving the file location? I would suspect the API expect the blob… @Phil_Seeman any idea?
It is possible to test it with Insomenia or I must to create it with Javascript
What is it? 
A rest api client where you can send http requests, same as Postman
Hi @Asaf,
I can’t tell for sure without seeing your whole request but it looks like you’re trying to pass just a filename. As @Bastien_Siebman says above, you need to pass the binary contents of the file.
You might find these forum posts helpful:
In terms of testing, I’m also not familiar with Insomenia but Asana provides a full collection of samples of their API calls for use in Postman here, including the “Upload an attachment” endpoint:
Hey, The problem I’m facing is only attaching a file using Postman/Insomnia for test purposes…
I’ve downloaded the Postman collection but I find that you don’t have this option to attach a file to a task built in… so I still need help over here.
I would very much appreciate it if you can let me know how can it be done…
I also attached 2 images that show that this step is existing on the Documentation but missing on the Postman collection.
Not sure why they organized it this way but it’s in the Postman collection under “Tasks”:
Hey, thanks for the help.
But, no matter what I’m trying I’m getting the same error…
Thanks
Thank you for the clarification!
