Update Task Status after sending mail reminder(with dynamic site link)



i have a daily scheduled flow, gets links of many sites (get items 1), then get tasks from each site (get items 2, based on apply to each value from get items 1) and process some functions.

i need to focus on the sending reminder to start a task, the trigger i use here is when all the predecessors are done.

i need to add after sending the mail, to update the task status to "in progress" instead of "not started".

knowing that site link is a dynamic value from the get items 1, "update" item don't help as it don't drill down to show me the task properties that i can change except if i put the exact link of a site.


i never used "send HTtp request" to sharepoint function and never used "Json", so please try to be detailed 🙂

tried the below in JSON but didn't work, also tried putting the same in HTTP REQUEST but looks i can't fill the headers and code properly!


in short words, the flow should send a mail reminder when all predecessors are done and its status is NOT in progress (which is working) , also need it to update the task as in progress (so it don't send a mail everyday saying task started)


  • {F39F007E-02B3-E911-BFC5-9061AE37BD41}
    • not sure if thats a unique value, as i copied the peek code from update item then tried to change the link, shall i leave this GUID blank? ("")
  • items('Apply_to_each_16')?['Project_x0020_subsite_x0020_Link']
    • that should get the site link as: MAIN SITE XX/XXX SUBSITE NAME XX/XXX SUB-SUB-SITE NAME XX
  • Project tasks'
    • Thats a fixed list name in all subsites where it contains the tasks i need to udpate.
  • items('Apply_to_each_3')?['ID']
    • that should return the task ID the flow is working on.



    "inputs": {

        "host": {

            "connection": {

                "name": "@parameters('$connections')['shared_sharepointonline']['connectionId']"



        "method": "patch",

            "Title": "",

            "Status": {

            "PercentComplete": 0,

            "Priority": {

                "Value": "(2) Normal"


            "SyncedProjectGUID": "{F39F007E-02B3-E911-BFC5-9061AE37BD41}"


        "path": "/datasets/@{encodeURIComponent(encodeURIComponent(items('Apply_to_each_16')?['Project_x0020_subsite_x0020_Link']))}/tables/@{encodeURIComponent(encodeURIComponent('Project tasks'))}/items/@{encodeURIComponent(items('Apply_to_each_3')?['ID'])}",

Adding the error message, sorry if its so basic 🙂 but i don't know how to use JSON


"status": 412,
"message": "The request ETag value '' does not match the object's ETag value '\"c4ecXXXXX83-42ad-a06f-eeeXXXX8a,5\"'.\r\nclientRequestId: 52eXXXX17a-ab2b-d19XXXX9\r\nserviceRequestId: 5fXXX-50c6-9XXXX6-0XXXX68",

Hi @AhmadH ,


On which step do you get the error message “The request Etag value doesn’t match the object’s Etag value”?


By the way, the error message “cannot evaluate the parameter ‘path.$.dataset’ at design-time” means that the token is using the dynamic content are expressions which evaluate only at runtime, so during design time i.e. when the flow is being created, the values of the dynamic contents are not available.


You may need to either select from the dropdown or type in correct value in those fields for dynamic values to work during design time.
