Stupid me got it, just forgot the 'f' parameter -> set to JSON in this sample. Anyway wanted to provide you my solution. token = arcpy.GetSigninToken() url="https://myorganization.arcgis.com/sharing/rest/content/users/username/9d0a35bf33c24f289e626b51f9asdf4578/items/123456782345678itemId/update" payload={ # THIS PARAMETER MADE THE DIFFERENCE 'f': 'json', 'description': 'Rest Test', 'overwrite': 'true', 'async': 'true', 'token': token['token'], 'title': 'RestTestFile', 'name': 'RestTestFile.csv', 'type': 'CSV', 'tags': 'RestTest', 'typeKeywords': 'CSV'} files={ 'file': ('RestTestFile.csv', open(file_path_variable,'rb'), 'text/csv') } # two kinds of requests with requests library response = requests.request("POST", url, data=payload, files=files) r = requests.post(url, data=payload, files=files)

Hi, I need to update a csv item in an ArcGIS Online Organization. For some reasones I need to do it without using arcgis python module. The idea is basically to generate a token and update the item by using the python requests library (or urllib). Somehow I cannot make it work with the requests lib. Help is appreciated! Thanks in advance folks :) token = arcpy.GetSigninToken() url="https://myorganization.arcgis.com/sharing/rest/content/users/username/9d0a35bf33c24f289e626b51f9asdf4578/items/123456782345678itemId/update" payload={ 'description': 'Rest Test', 'overwrite': 'true', 'async': 'true', 'token': token['token'], 'title': 'RestTestFile', 'name': 'RestTestFile.csv', 'type': 'CSV', 'tags': 'RestTest', 'typeKeywords': 'CSV'} files={ 'file': ('RestTestFile.csv', open(file_path_variable,'rb'), 'text/csv') } # two kinds of requests with requests library response = requests.request("POST", url, data=payload, files=files) r = requests.post(url, data=payload, files=files)

Yes made it :)

I have used this approach as well at some projects.

Just a short answer to global scope, yes I mean outside of the require statement. Have you tried to use the queryFeatures Method instead of queryObjectIds? I assume at the end of the day you want the features to be displayed in the bottom left corner. FeatureLayer | ArcGIS API for JavaScript 4.18

You could try to use the direct findLayerById Method of the WebMap class. Link below. WebMap | ArcGIS API for JavaScript 4.18

If you wanna use ArcGIS REST services you'll have to use the request class from the API which could look something like this: require([ "esri/allyourotherclasses", "esri/request" ], function (allyourotherclasses, esriRequest, ) { let serviceURL 'URLtoyourservice/arcgis/rest/services/MYSERVICE/gptool'; // this is the smaple data which has to be provided in unicode in the url // ?f=json&locations=[{"routeId":"60","measure":"0"}]&outSR=102100 let request = 'f=json&locations=%5B%7B%22routeId%22%3A%2260%22%2C%22measure%22%3A%220%22%7D%5D&outSR=102100'; let myURL = serviceURL += request; esriRequest(myURL, { responseType: 'json} ).then((response) => { console.log(response.data); }) }); Here is a link to the unicode converter I've used: https://www.url-encode-decode.com/ and here is the link to the ArcGIS REST API: https://developers.arcgis.com/rest/services-reference/get-started-with-the-services-directory.htm

Try to get your existing feature layer with the following logic (let is just another forma of declaring a variable which I personally prefer, you can as well use var). And don't get confused of (e) => { //code } it means the same as function (e) { //code } let myFeatureLayerTitle = 'TitleOfYourExistingFeatureLayer'; let myFeatureLayer = webmap.allLayers.find((layer) => { return layer.title === myFeatureLayerTitle; }); If you don't know the title of your layer you can also use the ID property or something else which identifies the layer. Additionally you can put the var view variable into the global scope (put it before the API require statement require([ ... ] ..... ) so you can use it in your browser dev tools and access your layers with view.map.allLayers.items

I copied your code and tried to recreate the problem and seems like the layer is not even loading that's why your find Method returns null. I can only provide you with a development hint to put the variable view into the global scope of your JS code, which makes it available in the browser console for easier debugging. What's important is that you should not forget to put the view variable out of the global scope again, once you ship your application in production mode.

Hi folks, I have a MapImageLayer which sublayer symbolizes roads of a country on a map. I want to sketch a rectangle over these Roads and get the intersection points (including the routes themselves) back. So basically what I have is the MapImageLayer, which features I can also query but the only thing I get back are obviously all routes - I need to query it based on the "rectangle selection" which is currentyl sketched in a GraphicsLayer using the SketchViewModel. Thanks in advance for your help!
