Qlik Replicate : Run task API command error

[ashishb]

we upgrade Qlik Replicate from 2022 Nov to 2023 Nov, after upgrade we are getting below error to run parent task  (db2 log streaming )

error {"error_code":"GENERAL_ERROR","error_message":"Value cannot be null.\r\nParameter name: name"} 

command : 
curl --silent -i -k -X POST --header "EnterpriseManager.APISessionID: ${session_id//[$'\t\r\n ']}" --header "Content-Length: 68" -d "{\"cdcposition\":\"Checkpoint:V1#1#00${offset}0001#0#0#*#0#0\"}" $host/attunityenterprisemanager/api/v1/servers/$replicate_name/tasks/"$(echo $line)?action=run&option=RECOVER_USING_CHECKPOINT_STORED_ON_TARGET"

I executed script with -x option and checked all variables are getting values. 

+ echo 'Starting the Log Stream tasks first, then other task from QEM '
Starting the Log Stream tasks first, then other task from QEM
+ curl -v -i -k -X POST --header 'EnterpriseManager.APISessionID: eQ6ETzc7K57g_xxxx' --header Content-Length:68 -d '{"cdcposition":"Checkpoint:V1#1#00DFxxxxxxx001#0#0#*#0#0"}' 'https://server.com/attunityenterprisemanager/api/v1/servers/replicate_host/tasks/Test?action=run&opt...'
Note: Unnecessary use of -X or --request, POST is already inferred.

I referred this page RunTask | Qlik Enterprise Manager Help

in this example :

C:\Windows\System32>curl -i -k -X POST --header "EnterpriseManager.APISessionID: qb-LIrTkfIRFczl8MLPT1w" -d "{\"cdcposition\":\"2024-03-07T11:19:03\"}" "https://10.76.246.205/attunityenterprisemanager/api/v1/servers/sql_104/tasks/sql2file?action=run&opt..."

error
{"error_code":"GENERAL_ERROR","error_message":"Value cannot be null.\r\nParameter name: name"}
 ===

Notes that this is a json format "{\"cdcposition\":\"2024-03-07T11:19:03\"}"

so the API call should have been :

curl -i -k -X POST --header "EnterpriseManager.APISessionID: 9VO3LNvPhX0yIqLv5W9_dQ" --header "Content-type: application/json" -d "{\"cdcposition\":\"2024-03-07T11:19:03\"}" "https://10.76.246.205/attunityenterprisemanager/api/v1/servers/sql_104/tasks/sql2file?action=run&opt..."

Thanks its working now.
But it was working on version 2022 Nov without adding "--header "Content-type: application/json" ".
