Params format for running workflow from API

1

Hi,

I’m trying to create a javascript program to run a galaxy workflow using the API.
I run the workflow and it is executed on the history I choose,
but tools’ parameters are not set. Workflow is running only with the default parameters defined on galaxy web interface during workflow creation.

My code where I call the API is:

    setWorkflowParams()

    const httpOptions = {
        headers: new HttpHeaders({
            'Content-Type':  'application/json'
        })
    };

    let dict = {};
    dict['workflow_id'] = 'f2db41e1ad331c3e';
    dict['history'] = 'hist_id=df6a1e0b02a5d08e';
    dict['parameters'] = params;

    return this.http.post(URL_GALAXY + '/api/workflows?key=' + API_KEY, dict, httpOptions);

And this is the code where I set the parameters dictionary on the variable params:

    setWorkflowParams() {
        let dictSarra = {};
        dictSarra['paramSolo_0|profRaiz'] = 0.5;
        dictSarra['paramSolo_0|reserva'] = 70;
        dictSarra['paramSolo_1|profRaiz'] = 0.5;
        dictSarra['paramSolo_1|reserva'] = 110;
        dictSarra['paramSolo_2|profRaiz'] = 0.5;
        dictSarra['paramSolo_2|reserva'] = 150;
        dictSarra['cult'] = 20;

        let dictCSV = {};
        dictCSV['fases'] = ['1','2'];

        let dictInter = {};
        dictInter['riscos'] = ['80','70','60','50'];

        let dictArea = {};
        dictArea['cortef1'] = 0.6;
        dictArea['cortef2'] = 0.5;
        dictArea['cortef3'] = 1.0;
        dictArea['cortef4'] = 1.0;

        let dictClass = {};
        dictClass['corteArea'] = 0.3;

        let dictParams = {};
        dictParams['0'] = dictSarra;
        dictParams['1'] = dictCSV;
        dictParams['2'] = dictInter;
        dictParams['3'] = dictArea;
        dictParams['4'] = dictClass;

        this.params = dictParams;
      }

My workflow has five steps (tools). I have searched the galaxy documentation and I’ve found this explanation only:

“parameters (dict) – If workflow_id is set - see _update_step_parameters()”

No further explanation is available on the code also. I’ve found these two links where it shows how to build the parameter “params”, which is the way I implemented the code in setWorkflowParams():

https://bioblend.readthedocs.io/en/latest/api_docs/galaxy/all.html#bioblend.galaxy.workflows.WorkflowClient.invoke_workflow
https://www.mail-archive.com/galaxy-dev@lists.bx.psu.edu/msg15083.html

Here is my params in JSON format, which I guess it follows the specification I found on those links:

    {"0":{"paramSolo_0|profRaiz":0.5,"paramSolo_0|reserva":70,"paramSolo_1|profRaiz":0.5,"paramSolo_1|reserva":110,"paramSolo_2|profRaiz":0.5,"paramSolo_2|reserva":150,"cult":20},"1":{"fases":["1","2"]},"2":{"riscos":["80","70","60","50"]},"3":{"cortef1":0.6,"cortef2":0.5,"cortef3":1,"cortef4":1},"4":{"corteArea":0.3}}

But that doesn’t work. Any ideas? Thanks.
