I'm getting "No project could be found with key 'ABC'." even though GET .../project/ABC works

[Malte Finsterwalder]

I'm trying to create a Jira component via the REST API.

I POST to https://my.atlassian.net/rest/api/3/component

In the POST request body I set:

{
"name": "Component 1",
"description": "This is a Jira component",
"project": "ABC",
"assigneeType": "UNASSIGNED",
"leadAccountId": "myaccountid"
}

A project with key ABC exists. And when I GET https://my.atlassian.net/rest/api/3/project/ABC
I get a proper response with:

"key" : "ABC"

So it's there and I have access to it.

But when I send the POST to create the component I always get a 404 back with:

{ "errorMessages": [ "No project could be found with key 'ABC'." ], "errors": {}}

And ideas, why this is happening?

I'm using Postman with an API Token. The user is a Jira Admin.

Hi @Malte Finsterwalder ,

I just created a component on my own instance via Postman. And there is no problem at all.

A 404 is returned if the project is not found or the user does not have permission to browse the project containing the component.

So the first is not the case, it should be the latter. Or it might be that Jira Admin is not a project admin and can't create components.

Thanks for trying that!

When I'm logged in with the same user in Jira, I can see the project and I can create a component.

When I do it through the rest API I can also see the project with all it's details, as described above. So I obviously have permissions to access the project.

In "Project settings"->"People" the group "jira-administrators" is present as Role "Administrators" and I'm part of that group.

I also added myself to the Project with Role "Administrators" but that still does not work.

Hm....

I can create a new project via REST API, but I still can't create a component in that new Project. I'm also the lead of that new project.

I still get "No project could be found with Key 'NEW'."

Is it a classic project or a next gen?

I've used a classic project.

[Malte Finsterwalder]

It's a classic project as well.

[Rudy Holtkamp _TMC_]

In that case...I've no idea left. Sorry.

I think you should contact Atlassian support to get this one sorted out. I do stay curious about what is the problem, so if they have figured it out, could you please report it here?

[Malte Finsterwalder]

Thanks for all your help! If I find the problem, I will post the solution here.

Hi @Malte Finsterwalder , Hope you've found the solution :) I'm running into the same challenge. When I open the URL directly in my browser when logged-in, all works well. But when running the same API GET in automations I get the issue:

"errorMessages": [
    "No project could be found with key 'XXX'."

Hi @Malte Finsterwalder and others with this issue. I found the solution! I had to add a header with an API key to allow access to the webservice that is hashed in base64 together with my email. (emailaddress:apikey)
