I am facing the challenge that I want to provide a GP tool on an ArcGIS Server 11.3, which should always use the credentials of the calling user when running. The call is made from an Experience Builder client so that I can customize the request accordingly. One possible solution would be to set up a separate parameter for the user token or the username. However, I don't like this solution for several reasons. I actually only want to receive the information required for processing in the parameters and not credentials. In addition, the signature of the tool would change. And I would have to do this for all my tools. I would prefer a transfer via the HTTP header. But I can't find a way to read the HTTP header in the context of an ArcGIS Server GP tool. An SOI doesn't seem to help either, as this can only be used for MapServices. Is it possible to access the HTTP header information within a GP Tool in ArcGIS? Are there any other ideas to realize this? ... View more

I have a phenomenon here and am wondering whether this is a bug or work-as-designed. We receive geometries from a routing service as polylines (saved as JSON) and we want to unite them geometrically with the union function. (We have no Z-coordinates, so we cant't detect if it is a crossing or a bridge or so on.) edge1_shape:arcpy.Polyline = arcpy.AsShape(edge1.Geometry, True) edge2_shape:arcpy.Polyline = arcpy.AsShape(edge2.Geometry, True) edge1.Geometry = edge1_shape.union(edge2_shape).JSON So far, everything is fine in normal line segments. Something strange happens when the line crosses, like here The polyline, which normally consists of exactly one “part”, is split at the crossing point, as soon as the circle closes (at the exact same crossing point wich has already been added before) Now another part is created. So far everything, so good. However, the part that was traveled first and was previously part 0 ... ... suddenly becomes Part 1 and the newly inserted part is now Part 0. As far as I know, new parts are always added at the end. And then to top it all off: If the third part is added after the crossing point, then the first part is the last part (Part 2), the second section is the first part (Part 0) and the last section is the middle part (Part 1) This means that there is no sequence at all. I don't know any longer, which part was added first and which is the last part of my line. It looks like a bug to me. ... View more

Hey guys, We are actually developing Web Tools based on ArcGIS Pro 2.8 to publish in ArcGIS Enterprise 10.8.1. We want to establish unit tests and want to run these tests in Azure DevOps Pipelines. While in a local environment I have an ArcGIS Pro installed, of course this is not the case in an Azure DevOps environment. And simply trying to install arcpy module with python install failed. What is the recommended scenario from Esri to establish this? Kind regards, Max ... View more

Hi guys, I have a strange behaviour with my script which I wrote for a customer. Just the relevant lines ... import arcpy import os import sys import logging import logging.config from datetime import datetime # CONFIG Paths Pdf_Path = r"C:\PrintServer" Log_Path = r"C:\PrintServer\log" Aprx_File = r"D:\data\PrintServer\COVID19_Print.aprx" def main(): # Input Layout template Layout_Template = arcpy.GetParameterAsText(0) #open the ProProject try: aprx = arcpy.mp.ArcGISProject(Aprx_File) layouts = aprx.listLayouts(Layout_Template) except: raise #print each layout found out_files = [] for lyt in layouts: try: now = datetime.now() tmp_file_name = lyt.name + "_" + now.strftime("%Y%m%d_%H%M%S") + ".pdf" Temp_File = os.path.join(arcpy.env.scratchFolder, tmp_file_name) #This line always results in an OSError lyt.exportToPDF(Temp_File, resolution = 300) Output_File = os.path.join(Pdf_Path, tmp_file_name) import shutil shutil.move(Temp_File, Output_File) out_files.append(Output_File) except: raise arcpy.SetParameter(1, out_files) if __name__ == '__main__': try: main() except: import traceback logging.error(traceback.format_exc()) The idea is to provide a GPService which takes a public WebMap, uses a predefined ArcGIS Pro Project (.aprx) also published with the GPService, reading a layout and printing this layout as pdf document. In my tests on my machine and three different ArcGIS servers, this has been no problem. Also running on the customers ArcGIS Pro client worked as expected, but when rolling out on the customers server, we always get an OSError when executing the ExportToPDF method.   What we already verified/tested: different file directories: hard coded temp folder or the scratch folder from arcgis shortened the file and directory names tripple checked write permissions, we have used different users, even full previliged from their IT department executed the script via GPService or via python shell, both results in the same OSError tested with ExportToJPG and ExportToPNG, both also produces the same error tested, if a PDF program is necessary (it is not) tested, if a PDF in general could be produced with python (is possible) So, this works: #Create the file and append pages pdfDoc = arcpy.mp.PDFDocumentCreate(pdfPath) pdfDoc.appendPages(referencePdf) pdfDoc.saveAndClose()   And now I don't have any other idea. Anybody of you have any? Has anybody a deeper look into that tool and can say, why this error could happen?   Kind regards, Max ... View more
