This message arises from a permissions issue that prevents Postman from accessing the files you intend to upload. This guide will provide a solution to this problem, ensuring a smooth file upload experience within your Postman environment.
What is Postman?
Postman functions as a one-stop shop for API development. Encompassing the entire workflow, it assists with design, testing, documentation, and management of APIs. Furthermore, it acts as a user-friendly interface for interacting with APIs, allowing you to send requests, examine responses, and effectively manage the entire lifecycle of API development.

Simplifying the Error's Meaning
The Postman error: 'Can't Select File at form-data, "Make Sure that Postman Can Read Files Inside the Working Directory" simply means that it was unable to upload a file. This file could be any eligible file, such as an image or other relevant files that may be included in an API request.
Potential Causes for "Can't Select File at form-data" Error
The error message "Can't Select File at form-data, 'Make Sure that Postman Can Read Files Inside the Working Directory'" usually arises due to a permissions issue that restricts Postman's ability to access the file you intend to upload. Here's a deeper exploration of the potential reasons behind this error message:
Misconfigured Working Directory
Postman utilizes a designated working directory to manage files associated with requests. If this directory is incorrectly set in the Postman settings, it will lead to the error message. The working directory might not be pointing to the actual location of the file you're trying to upload.
A thorough verification of the configured path within the Postman settings and ensure it accurately reflects the file's location is crucial.
Permission Impediments
Even with a correctly configured working directory, limitations on file system permissions can still trigger the error. These limitations could stem from restrictions imposed by your operating system or specific folder permissions that prevent Postman from accessing the file.
Investigating and potentially adjusting file system permissions to grant Postman the necessary read access might be necessary to resolve this issue.
File Path Discrepancies
The error message might also indicate an inaccuracy in the file path you've specified within the form-data section of your Postman request. A meticulous examination of the provided file path is essential. Look for any typos, inconsistencies, or incorrect relative path references that could be hindering Postman's ability to locate the file.
Potential Solutions to the "Can't Select File at form-data" Error
There are a few possible methods to fix this particular error, with one particular way being to ensure that your working directory points to the correct address within your system.
Ensure the Working Directory is Correct
As Postman is reporting that they do no have permission or access to retrieve the files you wish to upload onto Postman, double-check that the location of your working directory is correct.
Usually, the default Postman location provided should not cause an issue, however, if your file is in a more private and secure place, it may raise one.
However, if changing the working directory location does not work, it is suggested that you try to enable "Reading files outside working directory". The reason why this option is defaulted off is due to potential security issues. If you are certain that there are no sensitive or personal data found within the computer, you may consider turning this option on.
