Label-incoming-studies.lua

General

Hello,
I have an installation using the Orthanc Team and Authorization Service repositories. I’ve set up a Lua script “label-incoming-studies.lua” to add a label to each exam originating from a remote AeTitle. The script runs correctly, but I’m getting an error in the logs:
Access to a resource is forbidden: Auth plugin: no user profile or UserData found, unable to delete/put label with audit logs enabled

function makeValidLabel(input)
    local invalidCharacters = "[^%w_-]"   -- everything that is not alphanumeric or _ or -
    return input:gsub(invalidCharacters, "-")
end
  
function OnStoredInstance(instanceId, tags, metadata)
    print("OnStoredInstance ...")
    PrintRecursive(metadata)
  
    local parentStudy = ParseJson(RestApiGet("/instances/" .. instanceId .. "/study"))

    if #parentStudy.Labels == 0 and metadata.RemoteAET ~= nil and metadata.RemoteAET ~= '' then
      
        print("OnStoredInstance adding labels to parent study")
        -- RestApiPut("/studies/" .. parentStudy.ID .. "/labels/called-" .. makeValidLabel(metadata.CalledAET), '')
        -- RestApiPut("/studies/" .. parentStudy.ID .. "/labels/ip-" .. makeValidLabel(metadata.RemoteIP), '')
        RestApiPut("/studies/" .. parentStudy.ID .. "/labels/remote-" .. makeValidLabel(metadata.RemoteAET), '')
    end
  
    print("OnStoredInstance ... done")
  
end

thank you for your help

Hi,

setting the builtin parameter to true should bypass the auth-plugin and address directly the core Orthanc API:

Hope this helps,

Thanks Alain, it works now!!

I’m sharing the code with an aetitle mapping and a manual import;

All that’s missing are the different label colors depending on the case, and it will be perfect.
