Not able to access JIRA API's (Issue does not exist or you do not have permission to see it) Edited

[Tanuj Gupta]

Hi,

I am unable to get the result for JIRA API using postman. It is always telling me this error "Issue does not exist or you do not have permission to see it.". It is a trail tenant of JIRA.

In Posman, I tried using BasicAuth option by providing username and password (Password is the generated API Token).

Also I passed manually the header for "Authorization: Basic base64encode(<username>:<api_token>)" in HTTP request but that also failed. Can someone please help.

Hello @Tanuj Gupta ,

Thanks for reaching out, and I tested the call on postman without issue, so this should be working and is most likely a formatting issue on the Auth details in the call or permissions on the instance for the user.

The error message you are receiving:  

"Issue does not exist or you do not have permission to see it."

Is indicating a permission or access error, however, there could be a few different sources for it, as noted in the documentation for the endpoint HERE "This operation can be accessed anonymously."  so this is a generic error for any time portion of the auth chain conflicts there is a read issue occurring, where the server responds generically to not give back too much information about the authorization details used for security reasons.   i.e.: a malicious actor could do a brute force of calls against an endpoint to attempt to verify the existence of an account for follow-up actions so the details about the authorization are intentionally vague.

The things to check are:

1. Can the user access the issue from the UI? Check permissions in the instance
   1. if not set Project permissions for that user

   2. Permissions required:

      • Browse projects project permission for the project that the issue is in.
      • If issue-level security is configured, issue-level security permission to view the issue.

2. Is the username in an email format and is the email address valid?
   1. Check the username is formatted correctly as the user's e-mail used to log into Jira and is a valid user on the system
3. The Password should be the API token when using basic auth
   1. I recommend going to https://id.atlassian.com/manage-profile/security/api-tokens and revoking the existing token and generating a new one to make sure there is no conflict in the API token directly

Check these items out and let me know if you are still having an issue

Hi @Earl McCutcheon ,

Many thanks and thank you from the response. I am the administrator of JIRA, so I guess I am having the access of the issue.

Please note that I am using the gmail account email address.

As per your suggestion, I also logged-in using my username email address and I can browse the issue in UI successfully but still in Postman and even in NodeJS it is throwing the same error.

I also checked the username I am logged in using "My Profile" and it is having the same email address as I am giving to Postman or NodeJS.

Also when I am looking into Token ID, it is always telling me "Never Accessed"

Can you suggest if I am correct or wrong?

Hello @Tanuj Gupta ,

Thanks for the additional details and the screenshots, and first up having Global administrator permissions do not necessarily mean that you can see all issues, But as you can see the issue in the Browser then this is not the case and the permissions are correct to see the issue so all is good there. but just as a reference point details on project permissions can be seen in "Manage project permissions", but on a free plan do note that permissions cannot be edited and are locked out, but you can still check the permissions which is helpful if you run into any issues during migration between a paid instance or a server instance to the free platform as there are a few scenarios where the permissions can cause a lockout as they are not editable once converted to the free plan.

The next point comes from the last screenshot where the API token "MyDevTest" is showing as "Never Accessed" which indicates that the input of this token from Postman and the attempt from the HTTP request using the BASE64 encoded username had the token fail or is not using the correct format so the token was never truly accessed.

In Postman using the username and password directly the formatting for this should not have any whitespace, either leading or trailing, check to make sure that the two fields don't have any extra spaces that may have been inadvertently copied over in front of or after the input string. 

As for BASE64 encoding on the value additional details can bee seen in the following document but the format for generating this in Windows or a Linux/Unix/MacOS systems would be as follows:

• Basic auth for REST APIs 

Windows:

$Text = ‘user@example.com:api_token_string’ $Bytes = [System.Text.Encoding]::UTF8.GetBytes($Text) $EncodedText = [Convert]::ToBase64String($Bytes) $EncodedText

Linux/Unix/MacOS:

echo -n user@example.com:api_token_string | base64

Also as mentioned in the KB above, you may have triggered a CAPTCHA.  Try logging out and back into your Jira instance to see if the CAPTCHA is enabled as it may have been triggered from previous formatting issues in the input strings causing multiple failed login attempts, where your current connected user session in the browser is still intact via a verified token but the subsequent Postman calls are getting blocked with the new login attempts behind a captcha.

Earl
