How to pass data in a variable from webapp js to workflow js using postevent

I need to pass variable from webapp js to workflow js , we are using an external signal to trigger the workflow from webapp javascript.

 

when we use vars.variablename 

xtk.workflow.PostEvent('calledWorkflow','signal','', <variables varName= {vars.xyz} />,false)

 

it shows an error in webapp as it does not allow vars.variablename.

 

we have also tried ctx variable but in the workflow it is coming as undefined.

    On your webapp

    var abc= ctx.vars.abc;
var xyz= ctx.vars.xyz;

NLWS.xtkWorkflow.PostEvent("yourworkflow", "yoursignal", "", {variables: {"abc":abc, "xyz" xyz, }}, false);

    On your workflow

    logInfo(vars.abc+vars.xyz)

      Hello @prateek789 ,

      webapps do not have worklfow variables like vars. or instance.vars. they use ctx.vars. the postEvent is correct just push local variable (var xyz) or push context variable to the function (ctx.vars.xyz)

        Hi @prateek789

        You can try storing the ctx variables in some variable (eg. var A = ctx.abc) and then try to call it in the Post event or you can also try storing the output in some Option Variables and use them in your workflow.
