I am trying to batch-update multiple layers to all have the same Arcade content applied. I have found documentation on using a combination of Attribute Expressions / Text elements, but for the particular Arcade I am using, it only functions correctly if Arcade content is applied.  I have looked through the developer documentation and it does not appear to call out Arcade as a popupElement supported function.  Here is my current code, but ultimately I would like to remove the Attribute Expression and Text element and use Arcade as this works for hyperlinking out to URLs.    from arcgis.gis import GIS from arcgis.mapping import WebMap # Step 1: Connect to the Portal gis = GIS("https://portal.website.com/portal/", "username", "password") # Step 2: Access the Web Map webmap_item = gis.content.get("itemid") webmap = WebMap(webmap_item) # Function to clean popupInfo, remove attribute expressions, text boxes, and fields list def clean_popup(layer): # Update the layer title to remove ":" and references to "fields" if "title" in layer: original_title = layer["title"] new_title = original_title.replace(':', '').replace('fields', '', 1).strip() layer["title"] = new_title if original_title != new_title: print(f"Updated layer title from '{original_title}' to '{new_title}'") # Clean the popupInfo to remove attribute expressions, fields list, and text boxes if "popupInfo" in layer: popup_info = layer["popupInfo"] # Clear popupElements to remove Fields list, text elements, and any other custom elements popup_info["popupElements"] = [] # Remove fieldInfos and attribute expressions (expressionInfos) completely popup_info.pop("fieldInfos", None) popup_info.pop("expressionInfos", None) # Removes any existing attribute expressions # Remove other potential field-related properties field_related_keys = ['displayField', 'description', 'showAttachments', 'mediaInfos'] for key in field_related_keys: popup_info.pop(key, None) print(f"Cleaned popupInfo for layer: {layer.get('title', 'Unnamed Layer')}") # Function to add an Arcade attribute expression and reference it in a text element def add_arcade_expression_as_text(layer): if "popupInfo" in layer: popup_info = layer["popupInfo"] # Define the Arcade attribute expression arcade_expression = { "name": "customContent", "title": "Custom Content", "expression": """ var fieldsToExclude = ["OBJECTID", "OBJECTID_1", "SHAPE", "LAYERNAME", "GLOBALID", "SHAPE.STAREA()", "SHAPE.STLENGTH()", "CREATED_USER", "CREATED_DATE", "LAST_EDITED_USER", "LAST_EDITED_DATE", "LASTMODBY", "LASTMODDATE", "LASTSYNDATE"];

Adding a filter with checkboxes (like you can in Excel) would help manage content in AGOL\Portal. The use came when I was trying to filter on an owner, and there was no option.      ... View more

In migrating applications from WAB to Ex Builder, I am configuring pop ups via Arcade. The idea of the code below is to not display the fields in "fieldsToExclude", then display all other fields in every  layer for the webmap using the same code and hyperlink when applicable. The issue I have been having is I cannot find a way to have the pop ups display the field alias, where it is only displaying the field name. The second issue is that the pop up is not displaying the fields in order of how the service is published.      // General and URL Fields Formatting var fieldsToExclude = ["OBJECTID", "SHAPE", "LAYERNAME", "GLOBALID", "SHAPE.STAREA()", "SHAPE.STLENGTH()", "CREATED_USER", "CREATED_DATE", "LAST_EDITED_USER", "LAST_EDITED_DATE", "LASTMODBY", "LASTMODDATE", "LASTSYNDATE"]; var content = ""; var seenUrls = {}; // Function to format URL fields function formatURL(label, value) { return "<b>" + label + ":</b> <a target='_blank' href='" + value + "'>Click here for more info.</a><br/>"; } // Iterate over each field in the $feature for (var field in $feature) { var value = $feature[field]; var alias = field; // Use the field name as a fallback alias // Exclude certain fields and check if value is not empty if (IndexOf(fieldsToExclude, Upper(field)) == -1 && !IsEmpty(value) && Upper(value) != "NULL") { // Check if the field value is a URL and format accordingly if (Upper(Left(value, 7)) == "HTTP://" || Upper(Left(value, 8)) == "HTTPS://") { if (!HasKey(seenUrls, value)) { content += formatURL(alias, value); seenUrls[value] = true; } } else { content += "<b>" + alias + ":</b> " + Text(value) + "<br/>"; } } } return { type: 'text', text: content // this property supports HTML tags };     ...

I am working on a script that will create a Vector Tile Package from ArcGIS Pro and publish to Portal. In my testing portal environment, it functions as expected. When I switch the Portal URL, ItemIDs, etc to my production Portal, I get the below error.  ERROR - Error updating item PortalItemID: ('Failed to create Vector Tile Package MapName: Item with this filename already exists. [itemId=PortalItemID]\n(Error Code: 409)', None) Does anyone have any suggestions on what might cause this behavior to exist in one instance of Portal but not another? The environment is ArcGIS Enterprise 11.2.  ... View more

ArcGIS Monitor was deployed to monitor one of our ArcGIS Server machines about 3 months ago. There is one alert that has been maxed out or nearly maxed out since deployment titled "Connectivity - arcgis_server_metrics (%)". We deployed on 4/24/24, and it has been consistent since. Does anyone else have this appear as an alert consistently or have any tips? The metrics reference did not have much info on this. We are at Monitor version 2023.3.1.      ... View more
