<!-- Answer -->
To resolve the "Unauthorized request" error when connecting to Azure DevOps
Projects using the AzureDevOpsPlugin in version v1.0.beta, ensure that your
token is valid and has the necessary permissions. Here are the steps to
troubleshoot and resolve the issue:
1. **Check the Organization Setting**: If the `organization` field in your
connection is `None`, you may need to edit your token to set the organization
to "All accessible organizations".
2. **Verify Organization Name and Token Permissions**: If you have specified
an organization, ensure that the organization name is correct and that your
token has access to the organization.
Here is the relevant code snippet from the `test_connection` method in the
`AzureDevOpsPlugin` class:
```python
def test_connection(self, connection: AzureDevOpsConnection) ->
TestConnectionResult:
api = AzureDevOpsAPI(connection)
message = None
hint = None
try:
if connection.organization is None:
hint = "You may need to edit your token to set organization to
'All accessible organizations'"
res = api.my_profile()
else:
hint = "Organization name may be incorrect or your token may not
have access to the organization."
res = api.projects(connection.organization)
except APIException as e:
res = e.response
if res.status == 401:
message = f"Invalid token. {hint}"
return TestConnectionResult.from_api_response(res, message)
```
Additionally, the `AzureDevOpsAPI` class includes a method to handle
authentication and response status codes. Specifically, it changes a 203 status
code to a 401 status code when the token is invalid, which can help in
identifying the issue more clearly:
```python
class AzureDevOpsAPI(API):
paginator = AzurePaginator()
base_url = "https://dev.azure.com/";
@request_hook
def authenticate(self, request: Request):
token_b64 = base64.b64encode((':' +
self.connection.token.get_secret_value()).encode()).decode()
request.headers['Authorization'] = 'Basic ' + token_b64
@request_hook
def set_api_version(self, request: Request):
request.query_args['api-version'] = "7.0"
@response_hook
def change_203_to_401(self, response: Response):
# When the token is invalid, Azure DevOps returns a 302 that
resolves to a sign-in page with status 203
# We want to change that to a 401 and raise an exception
if response.status == 203:
response.status = 401
raise APIException(response)
def my_profile(self):
req =
Request('https://app.vssps.visualstudio.com/_apis/profile/profiles/me')
return self.send(req)
def projects(self, org: str):
return self.get(org, '_apis/projects')
```
Ensure that your token is valid and has the necessary permissions to access
the specified organization. If the token is invalid or lacks the required
permissions, you will receive an "Unauthorized request" error.
Additionally, when creating your Personal Access Token (PAT), make sure to
select "ALL ACCESSIBLE ORGANIZATIONS" for the Organization field. This is
highlighted in the configuration UI for the Azure DevOps plugin:
```tsx
{
key: 'token',
label: 'Personal Access Token',
subLabel: (
<span>
<ExternalLink link={DOC_URL.PLUGIN.AZUREDEVOPS.AUTH_TOKEN}>Learn about
how to create a PAT</ExternalLink>{' '}
Please select ALL ACCESSIBLE ORGANIZATIONS for the Organization field
when you create the PAT.
</span>
),
}
```
By following these steps, you should be able to resolve the "Unauthorized
request" error
