Summary14945: delete_participant fails to delete and gives no error back

When trying to delete participants using RPC, i get an empty array back along with error = null.

example from postman:

Post made:

"method": "delete_participants",
"params": {
"sSessionKey" : "LI_3IT00FvLyl~hscSVE7vnHTKuBJu9D",
"iSurveyId" : 795957,
"aTokenIds" : ["998877"]
"id": 1

{"id":1,"result":{"998877":"Invalid token ID"},"error":null}

Steps To Reproduce

1) Make a new user and give it rights to delete participants.

2) Add some participants.

3) Try deleting the participants. An empty array is received as a result.

The above 3 images also describe the problem. I have tried to make a java call as well as from postman.

I also tried with token id with the array brackets and also without strings. I also tried making the calls with key,value pairs.

I just tried to reproduce this issue, but it is working as expected.
There are two points that you need to correct.

  1. Problem is in the syntax you are using.
    Don't use quotes around square brackets.
    Use one of this formats for aTokenIds:

  2. aTokenIds should be Token ID, not Token.
    When you open "Survey participants" page, Token ID is in the first column from the left.

Sorry but I have the same issue
My post:
this works in 3.14
I've tested to the 3.20.2 and 4.0.8 all with the same error:
a) It doesn't get back a response
b) Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'LIMIT 1' at line 1
