Nope, sorry that English is not my first language and that may lead to some
misuderstanding.
To input in the form of JOSN string, and then DolphinScheduler automatically
parse it into the form of K-V is only a convenient way for us to set start
parameters.
I can also generate the K-V pairs before I call the StartNewProcessInstance
api.
The primary point is:
I think that in some cases, tasks accept not only K-V pair, but also accept
form-data in JSON string.
e.g.
ProcessDefinition api(/dolphinscheduler/projects/{projectName}/process/save)
This api accepts form-data parameter which can directly input JSON string.
Tasks in the ProcessInstance may have the same situation.
But when I'm trying to send a start parameter (K in string, V in JSON
string) , it leads to the exception.
Now DolphinScheduler can only accept (K in string,V in string). When I input
start parameters(K in string, V in JSON string), Jackson will report an
exception that cannot transform to Map<String,String>.
And that was what I mean.
