I trigger an automation by adding a queue item when a certain process on a server ends successfully. The server executes a powershell script which then authenticates and adds the queue items via the Orchestrator API
This worked fine until I upgraded to Orchestrator 20.10.3 on prem and and now the script fails with the Orchestrator reporting :
“Unsupported Media Type”,“status”:415
According to the documentation this authentication method is stil valid - have you got an idea what might have changed?
This is the authentication bit:
#Step 1: define variables
$tenantName = 'xx'#TenantName
$RPAuser ='xx'#RPAuser
$RPApassword = 'xx'#RPApassword
$RPAAuthUri = 'https://<ORCH_LINK>/api/account/authenticate' #URI to obtain Bearer Token
$RPADataUri = 'https://<ORCH_LINK>/odata/Queues/UiPathODataSvc.AddQueueItem' #URI to send new queue item to
#Step 2: Get an authentication token from Orchestrator
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
$postBody = @{tenancyName=$tenantName;usernameOrEmailAddress=$RPAuser;password=$RPApassword}
$headers = @{ContentType='application/json'}
$response = Invoke-WebRequest -Uri $RPAAuthUri -UseBasicParsing -Method POST -Body $postBody -Headers $headers | ConvertFrom-Json;
$token = ('Bearer ' + $response.result );

Thanks to UiPath support for pointing out the obvious .
#1) Orchestrator 20.10 uses the JSON headers properly, earlier versions must have had a different behaviour, otherwise this typo would’ve surfaced earlier:
It has to be Content-Type !
#2 since the Header is now processed, the body really has to be JSON, so you need to ensure that your Body is converted to JSON:
#Step 1: define variables
$tenantName = “xx”#TenantName
$RPAuser =“xx”#RPAuser
$RPApassword = “xx”#RPApassword
$RPAAuthUri = “<LINK_TO_ORCH>/api/Account/Authenticate” #URI to obtain Bearer Token
$RPADataUri = “<LINK_TO_ORCH>/odata/Queues/UiPathODataSvc.AddQueueItem” #URI to send new queue item to
#Step 2: Get an authentication token from Orchestrator
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
$postBody = @{“tenancyName”=$tenantName;“usernameOrEmailAddress”=$RPAuser;“password”=$RPApassword} $postBody = $postBody | ConvertTo-Json $headers = @{“Content-Type”=“application/json”}
