I'm building a library that uploads certain items to ArcGIS Portal or ArcGIS Online using addItem.  I found out that if the title contains either < or >, the title is stripped after that character. This is not just a display issue, I checked using the ArcGIS Assistant, and can confirm that the actual title of the item is modified My first thought was that I had to escape the form parameters in the POST request, and replace < with %3C etc, but that didn't fix it. Eventually it turned out that changing < to &lt; and > to &gt; does fix the issue, but this is strange because we are not in an HTML or XML context.  However, this made me wonder, which other special characters do I need to escape? I'm now using the .NET method HttpUtility.HtmlEncode() which encodes &<>\     (Note, I already found out that a + in a title is completely impossible due to an almost two year old bug) ... View more

I'm trying to access a protected feature service using the Maps SDK version 200.2, and would like to use an application login to do so.   My basic flow so far is this:   AuthenticationManager.Current.ChallengeHandler = new AppChallengeHandler(); var table = new ServiceFeatureTable(new Uri("https://example.com/arcgis/rest/services/Test/FeatureServer/0")); await table.LoadAsync();   and   internal class AppChallengeHandler : IChallengeHandler { public async Task<Credential> CreateCredentialAsync(CredentialRequestInfo requestInfo) { var challengeRequest = new CredentialRequestInfo { GenerateTokenOptions = new GenerateTokenOptions { TokenAuthenticationType = TokenAuthenticationType.OAuthClientCredentials, }, ServiceUri = new Uri("https://example.com/portal"), }; var serverInfo = AuthenticationManager.Current.FindServerInfo( new Uri("https://example.com/arcgis/rest")); serverInfo.OAuthClientInfo = new OAuthClientInfo( CLIENTID, new Uri("https://example.com"), CLIENTSECRET); serverInfo.TokenAuthenticationType = TokenAuthenticationType.OAuthClientCredentials; var creds = await AuthenticationManager.Current.GetCredentialAsync(challengeRequest, false); if (creds == null) { throw new Exception("Not authorized"); } return creds; } }     The call to LoadAsync triggers CreateCredentialsAsync, at which time a serverInfo object for the service is added to the AuthenticationManager. However, the code just stops at GetCredentialsAsync, no exception, nothing in the output window of Visual Studio, no request to be seen in Fiddler. Does anyone know how to do this? ... View more

I'm trying to login in ArcGIS Enterprise, using a fairly standard call: gis = GIS(portalUrl, user, pass)   This used to work, but now I get an error: 2023-03-07 10:08:59,110 - DEBUG - Connecting to portal: example.com 2023-03-07 10:08:59,114 - DEBUG - Starting new HTTPS connection (1): example.com:443 2023-03-07 10:09:00,029 - DEBUG - https://example.com:443 "GET /portal/info?f=json HTTP/1.1" 500 7058 2023-03-07 10:09:00,035 - DEBUG - https://example.com:443 "GET /portal/rest/info?f=json HTTP/1.1" 500 7058 2023-03-07 10:09:00,042 - DEBUG - https://example.com:443 "GET /portal/sharing/rest/info?f=json HTTP/1.1" 200 139 2023-03-07 10:09:00,048 - DEBUG - https://example.com:443 "GET /portal/rest/services?f=json HTTP/1.1" 500 7058 2023-03-07 10:09:00,157 - ERROR - Please ensure gssapi is installed 2023-03-07 10:09:00,171 - DEBUG - Traceback (most recent call last):   File "D:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\auth\_auth\_winauth.py", line 75, in __init__     creds = gssapi.raw.acquire_cred_with_password(   File "gssapi\raw\ext_password.pyx", line 75, in gssapi.raw.ext_password.acquire_cred_with_password gssapi.raw.exceptions.BadNameError: Major (131072): An invalid name was supplied, Minor (2529639136): Configuration file does not specify default realm  During handling of the above exception, another exception occurred: Traceback (most recent call last):   File "D:\Data\MOR\Migratie\Download-wf5.py", line 45, in <module>     main()   File "D:\Data\MOR\Migratie\Download-wf5.py", line 33, in main     gis = GIS(settings.ARCGIS_PORTAL_URL, settings.ARCGIS_USER, settings.ARCGIS_PASS)   File "D:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\gis\__init__.py", line 585, in __init__     raise e   File "D:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\gis\__init__.py", line 524, in __init__     self._portal = _portalpy.Portal(   File "D:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\gis\_impl\_portalpy.py", line 205, in __init__     self.con = Connection(   File "D:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\gis\_impl\_con\_connection.py", line 344, in __init__     self._create_session()   File "D:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\gis\_impl\_con\_connection.py", line 691, in _create_session     self._session.auth = EsriWindowsAuth(   File "D:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\auth\_auth\_winauth.py", line 84, in __init__     raise Exception("Please ensure gssapi is installed") Exception: Please ensure gssapi is installed   A few things to notice: Some requests to the portal return HTTP 500 The first error is Configuration file does not specify default realm .

One thing that did change is an upgrade to ArcGIS Pro from 3.0 to 3.1.   ... View more

In Pro, I can add some geodatabase functionality to many-to-many relationship classes, e.g. editor tracking, global ID's and archiving. This will add the appropriate fields to the intermediate (or 'junction') table. When I do this, I can, for instance, add the intermediate table to a featureservice, to take it offline.   How can I do this using arcpy? ... View more

Hi, I have a mobile application where users, beside a normal basemap, use about 50 layers with more or less static reference data from a feature service. The total size of the data is not very big, roughly 50MB I noticed that the number of layers has a large impact on startup time for the app, and also when synchronizing to go offline. My first idea was to create a tiled vector package, and add it to a local mmpk which already contains a topographical basemap, and aerial photography. This actually works really well performance wise, but when doing this, users can no longer turn individual layers on and off because basemaps are shown as a single layer. I also thought about using a local file geodatabase, but I don't see an easy way to apply symbology in the app. Or is there a concept similar to layerfiles in ArcGIS runtime? I haven't found anything yet. What would be the best way to go about this? ... View more

How can I add records to a many-to-many relationshipclass in ArcGIS Server using the REST interface?   For a one-to-many relationship it's easy, as you can just grab the foreign key from the source table, and use that to insert (or update) records in the destination. However, with many-to-many, we would need to add a record to the junction (or 'intermediate') table. I can't seem to find any information about this. ... View more
