Inject dynamic data in Serverless workflow

[Pablo]

Hi,

I'm trying to define a serverless workflow, where in some states i may add dynamic data.

I used "inject" type state to add to data field some new parameters to the json message, but it seems I cannot inject data such as referenced fields.

Example. Pay attention only to $.{} fields, as they are already part of the previous message shared among states. I'm also interested in using conditions to decide data.

Is it possible?

Best regards and thanks in advance

{

"name": "InjectTask",

"type": "inject",

"data": {

"version": "0.0.1.0",

"id": "-",

"timestamp": "$.time",

"ker": "robot",

"message": "task",

"data": {

"taskID":"${WORKFLOW.instanceId}",

"taskType":"moveTo",

"taskStatus":"pending",

"priority":"none",

"startTime":"${.time}",

"endTime":" ",

"startLocation":" ",

"endLocation":"${.room}"}

},

"transition": "WaitForResult"

},

Hi Pablo!

The inject state is for static data only [1]. Why not use action data filters [2] in the operation state and add a jq expression to model the data the way you need using "toStateData"?

Cheers!

Hi Ricardo,

can I use fields form the whole cloudevent structure  with data filters or just fields inside data field?
