Hi, we have a keycloak sitting in front of our ArcGis Portal Server that requires a bearer token for authentication. I found out that I can add a header using ArcGISEnvironment.arcGISHttpClient.addAdditionalRequestHeader()
Adding this token to the HttpClient, allows us to succesfully pass the keycloak, but when the download starts using OfflineMapJob.start() the downloads fails with the following error:
Failure(com.arcgismaps.exceptions.ArcGISAuthenticationException$InvalidTokenException: message=Invalid token., additionalMessage=Failed to load offline map task.
An invalid token was used to access https://myserver/arcgisserver/rest/services/Hosted/myBasemap/VectorTileServer., errorCode=18006)
We tested the code without keycloak and without the additional authentication header and the download worked well before. Hope you can give us a hint on how to set a bearer token successfully.
Edit: We added some logs. It seems that from the definition of the OfflineMapTask, the proxy server is no longer present in any url that accesses the portal or the arcgis server rest inferface (/rest/...). Thus, our app tries to bypass the proxy and directly access the resources on the rest interface and fails for two reasons:
- The URL cannot be reached, since the proxy is no longer addressed but the hostname behind the proxy.
- The request contains the bearer token which is assumably interpreted by the rest interface as an arcgis authentication token.
Here is our log where "myproxyserver" is the hostname of our proxy and "myarcgisserver" is the host behind the proxy that we can not reach from our mobile device. The error occurs when the OfflineMapTasks loads.
