Azure Digital Twin CLI error

Seiya Zelin Shen 72

I have a question on the website

https://learn.microsoft.com/zh-cn/azure/digital-twins/how-to-ingest-iot-hub-data?tabs=cli

when I run the create model or create twin as cli, it shows the error as following:

may I know how is the error ? the cli command is :

az dt twin create --dt-name <instance-name> --dtmi "dtmi:contosocom:DigitalTwins:Thermostat;1" --twin-id thermostat67 --properties '{"Temperature": 0.0,}'

az dt model create --dt-name <instance-name> --models '{ "@id": "dtmi:contosocom:DigitalTwins:Thermostat;1", "@type ": "Interface", "@Георгий Георгиевский ": "dtmi:dtdl:context;2", "contents": [ { "@type ": "Property", "name": "Temperature", "schema": "double" } ]}'

many thanks.

@Seiya Sum Welcome to Microsoft Q&A forum!
Could you please confirm how exactly you are running the CLI commands? Is it through portal directly or through CLI from your machine?

I followed the doc as by using Try it option and able to create model correctly without any issue. Please see below.

From the screenshot you have shared, error occurred due to the incorrect syntax. You have specified (double quotes) "" for temperature values.
Also, you have mentioned, you tried with different options as well. I would suggest you, delete the existing model and run the command again and see if it makes any difference.

You can delete the existing models from Azure Digital Twins Explorer. You can access Azure Digital Twins Explorer from the Azure portal.

Hope this helps. Do let me know if you have any further queries.

Could you confirm how exactly are you running the scripts?

As mentioned earlier, Your script is failing due to incorrect syntax at the end of CLI command. i.e You have specified (double quotes) "" for temperature values.

You need to specify the command without double quotes to resolve this error for --properties '{"Temperature": 0.0,}'

Correct syntax is

az dt twin create --dt-name <your instance-name> --dtmi "dtmi:contosocom:DigitalTwins:Thermostat;1" --twin-id thermostat67 --properties '{"Temperature": 0.0,}'

Also, please check Azure Digital Twins Explorer and delete the existing model with the name "dtmi:contosocom:DigitalTwins:Thermostat;1" if any

Please let us know if you have further queries. We are happy to assist you further.

Answer 1

Hello @Seiya Sum Thanks for reaching out on this forum!

Thanks to @AshokPeddakotla-MSFT for the repro and validating the documentation on cloud shell.

After working offline with you on this issue, here is the summary\outcome which details the solution.

when I run the create model or create twin as cli, it shows the error as following:

----> unrecognized arguments: 60.6,}'

Fix\Workaround: When you create a twin with the CLI, depending on what type of command prompt you're using, you might have to escape the " characters

az dt twin create    
             --dt-name myADTsoutheastasia.api.sea.digitaltwins.azure.net   
             --dtmi "dtmi:contosocom1:DigitalTwins:Thermostat;1"   
             --twin-id thermostat67   
             --properties "{\"Temperature\": 60.6,}"

Documentation: We are updating instructions on the documentation as well for this CLI command usage.
