Update Context params with MetaservletAPI updateTask does not work with Talend v8.0.1

[Safus]

This metaServletAPI call does not insert new context values to the already existing task.

{

 "actionName": "updateTask",

 "authPass": "XXXXXXX",

 "authUser": "XXXXXXXX",

 "context":{"varname1": "varvalue", "varname2": "varvalue2"},

 "taskId": 10,

 "timeout": 3600

}

I can see the timeout value being updated but not the context params. (No parsing problem ... )

I know that I can directly insert some rows in Database but for me it's the ugliest and most unrecommended solution.

Is it a new bug ? or the call is somehow wrong ?

Hello

I look into the metaSevlet API documentation, the updateTask command allows customize value and make it enabled for context.

Go to check if it works with only one variable.

{

 "actionName": "updateTask",

 "authPass": "XXXXXXX",

 "authUser": "XXXXXXXX",

 "context":{"varname1": "varvalue"},

 "taskId": 10,

 "timeout": 3600

}

with 2 or more variables.

{

 "actionName": "updateTask",

 "authPass": "XXXXXXX",

 "authUser": "XXXXXXXX",

 "context":{"varname1": "varvalue";"varname2": "varvalue2"},

 "taskId": 10,

 "timeout": 3600

}

Hello @Shicong Hong​ 

I have already tested with one value but it does not work.

But the endpoint can update a value of an existing context variable and it does not create a new variable.

Is is a bug or is it what it is was developed for ?

Is there a way to create a new custom context variable for a task ?

@safouane BEN MANSOUR​ , the context parameter here is used to pass a new value, rather than creating a new variable, the context variable must be defined in the job in studio.
