I think you are misreading the debugger display. The bit you are missing is the last few characters in the evaluation display, after the closing parenthesis. They should not be there if it is displaying a dictionary. Evidently the variable 'aDict' is in fact an association whose key is the dictionary and whose value is nil.
I can't see where it goes from there, but I think you need to look more closely at the preceding line, FAOEntry>>getEntryObjectFrom:, and see what exactly it does with the junk in your .dat file.

Subject: [Pharo-users] Re: Problem with Dictionary and Associations
Thank you for that but it doesn���t resolve my problem. Why does the stack move to an Association when doing the access to the dictionary? It is the Association indexing that fails as it won���t allow #entryAmount as a key.
If I inspect the following code (STON fromString: result ) in the line ^ self makeObject: (STON fromString: result ) I get an Association. Why don���t I get a Dictionary. I did two days ago when all of this was working perfectly and we were happily matching the Pharo Seaside display to our bank account :=)

I can parse the file data you provided:
STON fromString: '{#entryName:''Housekeeping'',#entryDate:Date[''2021-02-25Z''],#transactionID:''2021022501'',#entryAmount:-400/1s8,#entryCategory:''Housekeeping'',#entryDescription:''Housekeeping'',#match:nil}ousekeeping'',#match:nil}'
"a Dictionary(#entryAmount->-400.00000000s8 #entryCategory->'Housekeeping' #entryDate->25 February 2021 #entryDescription->'Housekeeping' #entryName->'Housekeeping' #match->nil #transactionID->'2021022501' )"
(BTW, this is STON not JSON).
What I do see in the input is junk after the last }
That can happen when you overwrite an existing file with shorter content. You should truncate such a file.
From your screenshot I can see nothing wrong, #entryAmount seems an existing key in aDict, that should just work.

I attach a couple of screen shots and a file containing the item that I am trying to open. What else can I supply? This has been working for a couple of weeks and suddenly doesn���t work. I save the JSON and then load it back again. I enclose a file with the JSON as contents. As you can see from the screenshot, the debugger shows it as a dictionary but the execution path takes it to an Association which is what I don���t understand.

Hi David,

I am using STON to objects out to disk. Up to two days ago, I was reading them in as Dictionaries and converting to objects from there. All of a sudden yesterday morning, I got an error saying that the association is only indexable with integers. Even so, I don't seem to be able to access the contents.
Fistly, any ideas why this has changed and secondly, any ideas how to fix it?

I am afraid I need more information.
Could you create a reproducible case ?
Do you have a stack trace ?
In any case, STON is a text format, that can be edited (in most cases, shared or circular references being hard to edit by hand).
