JSON sub-diagram within the ction works only for an array JSON

Question

This works:

@startuml
start
:file f
{{json
[{
    "a":"b"
}]
}}
;
stop
@enduml

while this doesn't:

@startuml
start
:file f
{{json
{
    "a":"b"
}
}}
;
stop
@enduml

Hello R.,

Yes it is an issue (perhaps already reported, I don't remember...).
It is due to the curly bracket management, here is a workaround proposal... use YAML  , as:

@startuml
start
:file f
{{yaml
a:b
}}
;
:test with curly B}
stop
@enduml

If that can help,
Regards,
Th.

Thanks! YAML could be the answer.
