Help Studio

Hi UiPath Community,

In my current project, I’m passing a screenshot, converting it to a Base64 string, and storing it as a text file in a Storage Bucket. I want to retrieve this text file in an Output Argument and send it back through Postman.

Could anyone guide me on how to:

  1. Retrieve the Base64 string from the text file stored in the Storage Bucket.
  2. Return this file as an Output Argument in Postman.

  1. Download file Activities - Download Storage File
  2. Then read text file
  3. Use the output of read text in http

Hello @Anil_G ,

Thanks for responding.

I am taking a screenshot and converting that in Base64 string is too long to include in the output, so I saved it as a text file in a storage bucket. ​As I am getting

"Exception: Output Arguments too large at 1049 kilobytes. The limit is 1024. Try using storage buckets to handle large data."​

​basically, I am not able to base64 string of Screenshot in orchestrator
​How can I retrieve this text file using Postman? As an output argument?

where are you getting this error?

what step are you performing?

If you want to access the storage bucket from postman you have orchestrator api

The image displays an API documentation interface for managing "Buckets" with various HTTP methods like POST, GET, DELETE, and PUT, including endpoints for bucket and file operations. (Captioned by AI)

you might first need to create an external app and then connect to api

On orchestrator getting this error.

Steps:
In my application, I have a login page. I pass the login ID and password as an input argument through Postman. After that, I take a screenshot of the web page and get its Base64 string in the console output. Due to an error, I store the string in a text file using a storage bucket. Now, I want to get that string as an output argument. How can I retrieve the text file as output? Is there another way to do this?
