system.util.jsonEncode output not the same in webdev module

Jean-Maurice_Dubois · September 23, 2025, 12:29pm

After upgrading to ignition 8.3, something broke with the system.util.jsonEncode function.

If the call is made from the webdev module, some key-value pair will changes to dictionaries?

system.util.jsonEncode called from WebDev:

system.util.jsonEncode called from project script or message handler:

Webdev in 8.1 would generate the same output. (the desired output)

Am I missing something?

Thanks

What is the object you are encoding? Can you add some debug logging e.g. print type(value) before passing value to system.util.jsonEncode?

Jean-Maurice_Dubois · September 23, 2025, 12:38pm

Sure can,

Type is dict:

here the code in webdev:

the output : is a key that contains an array.

each item in the array:

What's the type of the thing in a message handler? What are the contents of the dict? Can you compare them?

The behavior of jsonEncode doesn't change based on where you call it from. The only difference here can be that you are passing slightly different objects to it somehow.

the sendRequest sends back a list

Jean-Maurice_Dubois · September 23, 2025, 12:45pm

this is the message handler:

the commented line, that what it was before I change to 8.3 to get my result.

now if I encode here, no problem.

modified webdev part, this gives me what 8.1 did.

Kevin.Herron · September 23, 2025, 12:53pm

What kinds of things are in the res list?

It seems that whatever they are, they might not be getting serialized/deserialized when returned by sendRequest the same was as in 8.1, or may be entirely different now.

@paul-griffith do you recognize that dataType/value pair? Is this maybe some protobuf RPC thing?

Jean-Maurice_Dubois · September 23, 2025, 1:56pm

remark: I did change from java serialization to protobuf in gateway settings.

On the gateway that handles the message, can you set this logger to TRACE:

metro.serializers.ServerMessageSerializer

Then run your test again and post the logger entry? It would help to see the response data just before it is Protobuf serialized.

maybe it would be esaier to use the test project I have uploaded in this thread (see up)

Ok we figured it out. It’s because the values are in a list, which is triggering a bug in one of the deserializers. I put in a ticket to get this fixed ASAP. Thanks for the simplified examples, they made this much easier to replicate.

Jean-Maurice_Dubois · October 31, 2025, 1:09pm

Hi,

Version 8.3.1 fixed all the above but there is still something happening in the script console.

For example:

Webdev module, call a fonction on another gateway. Works fine, I get a result.

I have a script that call the same fonction, same parameters (for my example):

At the end, this sends a email

this gets call by a Scheduled script:

I do get my email, all si fine.

but if I call the same fonction in a script console (for debug purpose for example) and :

Java Traceback:

The script console is not gateway scope. Anything in your script that requires gateway scope will break.

You simply cannot debug such code from the designer script console. Sorry.

paul-griffith · October 31, 2025, 4:00pm

Interesting. You're using sendRequest - can you share the rest of your code or at least the portion where you assemble a value to return from the function you're calling?

While this is true, I don't think it's relevant here. They're apparently implicitly calling sendRequest in this library function, and that's the call that's failing.

Jean-Maurice_Dubois · October 31, 2025, 4:33pm

Sure.

Message handler:

Function:

def getDetails(startDate, endDate):

output = []
lstRecipe = AB2.PL03.Recipe.listBetween(startDate, endDate)

for i in range(len(lstRecipe)):
	
	bundles = AB2.PL03.Sorter.getProdOutput_Bundle(system.date.parse(lstRecipe[i]['startDate']), system.date.parse(lstRecipe[i]['endDate']))
	products = AB2.PL03.Sorter.getProdOutput_McxPMP(system.date.parse(lstRecipe[i]['startDate']), system.date.parse(lstRecipe[i]['endDate']))

	objCnt = {}
	objCnt['bundleIn'] = util.historian.counters.std("[CHIBOUGAMAU]CCL/CHIBOUGAMAU/AB2/PLANEUR/DECANTEUR-01/EDGE/Pqt_OK_Decanteur", \
													 lstRecipe[i]['startDate'], lstRecipe[i]['endDate'])
	
	objCnt['bundleOut'] = bundles['bundleOut']
	objCnt['sorterPieceCount'] = products['sorterPieceCount']

	lstRecipe[i]['oee'] = {"D" : 0, "P": 0, "Q": 0, "OEE": 0}
	
	output.append(lstRecipe[i])

return output

Here is a response sample:

response.json (662 Bytes)

example

Jean-Maurice_Dubois · October 31, 2025, 4:44pm

I do not know why in the stack trace shows the number has a float.

It should be an int.

We are breaking at this position in the response.

paul-griffith · November 3, 2025, 4:51pm

Can you share this function? (If you're more comfortable direct messaging me, that's fine too).

I'm asking because of this line:
output.append(lstRecipe[i])

I don't think there's any problem in the JSON you're ultimately assembling - the problem is somewhere in the Python dictionary structure to JSON conversion we're doing automatically.

Jean-Maurice_Dubois · November 3, 2025, 5:22pm

Here is an example of the output of this function:

So basically, I get the list of the recipe ran that day. Add some data to each “eventId”.

When done, add result to output list.

After all compiled, return results (output)
