REST API failure: Invoke-WebRequest : 404

The Powershell code bellow writes and reads values to Google Sheets (works fine) and should run the function myfunction in an Apps Script project using API, but Invoke-WebRequest returns the error bellow:

Invoke-WebRequest : 404. That’s an error. The requested URL /v1/scripts/=ya29.a0Ae4lvC3k8aahOCPBgf-tRf4SRFxdcCE97fkbXLAJqZ4zRCLnBp9prwEcBYBAf

I am not sure if the JSON representation of request body is set correctly or if the error was caused for something else.

Powershell Code:

EDIT:

Google App Script code:

function toSpreadsheet(text2write)
  {
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("HIL_APP");

  for (var i = 1; i < sheet.getLastRow(); i++)
  {
    sheet.getRange(i+1, 8, 1).setValue(text2write)
  }
  return "myreturn"
}

function myfunction(params)
{
  toSpreadsheet(params)
}

• You could confirm that the script for writing and reading values for Google Sheets worked fine.
• You want to modify only the script for running the Google Apps Script using Apps Script API.
  • You have already been able to use Apps Script API.
  • Your access token can be used for running the Google Apps Script.
• You want to achieve this using Invoke-WebRequest of powershell.

Modification points:

• From your error message and your script, I would like to propose the following modification points.
  1. From "https://script.googleapis.com/v1/scripts/$scriptId:run?access_token=$($accessToken)" to "https://script.googleapis.com/v1/scripts/${scriptId}:run"
     • In your script, the endpoint is https://script.googleapis.com/v1/scripts/. This is incomplete endpoint.
     • I think that the reason of your current error message is due to this.
  2. Please use the access token at the request header instead of the query parameter. Ref
     • I think that this can be also said for using Sheets API.
  3. I think that "attempt" string is "attempt".
  4. Please modify ” to ".

Modified script:

When the request to Apps Script API in your script is modified, it becomes as follows.

$scriptId = "1eF7ZaHH-pw2-AjnRVhOgnDxBUpfr0wALk1dVFg7B220bg_KuwVudbALh"

$json = @"
{
  "function": "myfunction",
  "parameters": ["attempt"],
  "devMode": true
}
"@

$resp = Invoke-WebRequest -Uri "https://script.googleapis.com/v1/scripts/${scriptId}:run" -Method Post -ContentType "application/json" -Body $json -Headers @{"Authorization"="Bearer ${accessToken}"}

Note:

• In my environment, I could confirm that above modified script worked. Unfortunately, I cannot understand about your flow for setting to run the Google Apps Script with Apps Script API. So if in your environment, an error occurs, please confirm the settings for running the script with Apps Script API, again.
• I think that "Bearer ${accessToken}" can be also modified to "Bearer $accessToken".
