We are trying to call a service on the Thingworx platform, not directly, but via the EMS channel.  Our assumption is that once our EMS communication channel has been established, we can make REST calls to the EMS and our REST call will travel to the Thingworx platform to where the execution of the service will take place.  We are making this REST call on the same PC as our EMS is running but are running into "401 Authentication Required" errors.  In our config.json, we have ssl and certificates enabled.   Using Postman, we POST: https://localhost:9000/Thingworx/Things/<Thing name>/Services/WhatsMyName  (note the use of https)   In our header we pass the appKey = <app key>, Content-Type = application/json, Accept = application/json, x-csrd-token and x-thingworx-session = false.   No matter what we seem to try, we just get the "401 Authentication Required" error.  We assume this error is on the EMS side and not the Thingworx p

Hi team,   I just started using Thinkworx and I am trying to get all the tags from Kepware Server to a Thingworx Foundation. But Kepware tag value is not updated in Thingworx Foundation. When I refresh "Industrial Thing" in Thingworx, the value is not updated. Kepware Server version: 6.9 Thingworx Foundation Version: 9     I was referred to the following guidelines.   https://developer.thingworx.com/en/resources/learning-paths/connect-and-monitor-plant-equipment/connect-kepware-server-thingworx-guide/bind-industrial-tag   https://community.ptc.com/t5/ThingWorx-Developers/How-do-I-simulate-random-tag-values-against-a-device-in-kepware/td-p/545582   In OPC Quick Client, Tag values are updated.   And one more thing. When I startup the Kepware server, it shows one info as "The specified account does not exist". I have attached the log details image file.

In one of the mashups in my company's Thingworx application, we show a percentage as the pie slice's value: The users would like to see '58.8%' for the value, but my team is struggling to find a way to append that. The ValueFormat property appears to only control the numeric formatting. We haven't been able to find the HTML that appears for it so that we might try some Custom CSS magic.   Can this be done with the widget?

I'm still trying to get the DropDown widget to work properly. This time the problem is that the usernames are not being displayed in the menu of the widget. I think I've got the needed connections in place, I may be missing one, though. I'm not sure. If I use the "View Mashup" button, I get an error like this:   Failed to load resource: the server responded with a status of 500 ()   that points to the GetUsersofAdmin service. As I'm  sure you are aware this usually points to a missing permission somewhere, but I can't find it. I've double checked all of the needed permissions that I can think of. The weird thing is that if I use a private window to log into the correct FormLogin to check the errors that come up when I log in with a specific user, I don't get any errors. It seems to be working properly, but the DropDown menu doesn't show any data. I've attached a picture of the connections. Thanks in advance.

Hi,   I have a question, what's the real advantages of ThingWorx Flow comparing to JavaScript Service ?   Here are some of the possible advantages and the corresponding objections :  "Flow provides lots of OOTB connector".  --- But if the implementation of connectors are exposed as services in Resources things,  JavaScript service can also call it without using Flow "Flow allows user to map and route between services without coding".  ---  But it's not big deal to implement mapping and route in JavaScript service,  Thing model design and the logic of data transformation are the main work in a project . "Flow ensure the calling sequence of each node,  while JavaScript cannot .  "  ---  This is what I heard , but I don't believe it .   I have written tens of thousands of lines of JavaScript service code and never see any disorder problem between JavaScript service.  And if this point is true , JavaScript ser

HI, In Thingworx is there a way by which I can execute a service, through passing the name of the service as parameter from another service? To be more clear, consider the following snippet --   I have two services in a thing 'Thing_Example' as 'srvA' and 'srvB' Defination of 'srvA' -- Inputs: serviceName; Type: String; Value: 'srvB' Service body -- var result = Things["Thing_Example"][serviceName]; //At this point I am expecting that 'srvB' should be executed   Thanks and Regards Aditya Mittal

Hi Team,   Have implemented one functionality in which I upload image via File Upload widget in repository and then display it immediately over image widget by creating media entity dynamically via service after clicking "Upload" button of file upload widget.   What actually happens it displays image correctly when I upload first time. It properly creates new media entity and displays over image widget immediately. But when I updates the image at the same time then it updates the image only at the media entity level but not refreshes on mashup.   Can somebody help me on this.   I am using code:-   var params = {name: mediaEntityName /* STRING */,content: imageContent /* IMAGE */}; // no returnResources["EntityServices"].UpdateMediaEntity(params);   My thingworx is 8.3.   Thanks in advance.
