"Map Service register Layers" python script error

[ChristopherBoland]

I've been using this script successfully for months now to register large Map Services in ArcGIS Online to be included in OpenData, but recently (the last couple of weeks) I've been receiving this error:

     {'error':{'messageCode': 'CONT_0057', 'message': "Invalid JSON in 'text' parameter.", 'code': 400, 'details': []}}

I don't think anything has changed on my machine(s) and I'm not doing anything differently when creating my Map Service.  What am I doing wrong?  I've attached the whole python script.

Hi Chris,

   I'm experiencing the same as you. If I get an answer I'll post here.

Chris,

Can you add a Try/ Except block around the res = agol.addItem... line of code?

In the except block it would be useful to Print serviceLayer.name.

That will help us debug what's being sent over to AGOL.

Hi Daniel Fenton​,

Thanks for the suggestion.  As you said, I added the try statement before the indicated lines of code and added the

     except:

          print serviceLayer.name

statement after it and received the same results.  It runs through all of the items in the service, prints the feature class name and the feature class description, then throws this error:

{'error': {'messageCode': 'CONT_0057', 'message': "Invalid JSON in 'text' parameter.", 'code': 400, 'details': []}}

Would you rather work offline with this?  Also, FYI, I also put a note on GitHub and received an email from Scott Moore (the code developer) yesterday saying that he would try to look into it.

[DanielFenton1]

Yes, but what is the name of the service?

[ChristopherBoland]

That's what I'm saying.  The script runs through all of the layers in the web mapping service, lists the name of the layers, lists the description of the layers, but doesn't create an AGOL item for any of them and throws the error.  It is not any one particular layer in the service and has occurred on many different web mapping services too, so not service specific. 

Currently I am trying it on this service:

Attached is the result of the script after running in IDLE:

Hey there!  I just added a new script on GitHub that uses the latest version of ArcREST.  You can find it here:

here.

You need to download the latest version of ArcREST as well.  I made a note in the ReadMe.

When I try to run the new version against your service, I get this stack trace.  Maybe there is some sort of network equipment that is blocking certain requests?

Thanks Scott!

I downloaded the new version of your script and installed ArcRest v2 and it ran perfectly on that rest endpoint.  I don't know why you were getting the stack trace, but it worked fine for me.

Thanks again,

Chris

Looking at the Add Item API documentation you’ll see that there is a “text” option for Items. That is likely what the error is responding to. However you are not explicitly trying to include a text parameter.

You could use Fiddler or other to capture the JSON being sent to AGOL – that would be the best way to see what you are sending. I’m curious if a “text” is getting added in the ArcREST (though looking at the source I don’t see that).

Alternatively you could add a text parameter that is a blank string. Maybe AGOL is now expecting the parameter (though it probably shouldn’t).
