Rest APi Update iRule

Hi There

 

I have been researching this all day and cannot seem to get a solution. I am trying to "Update" an iRUle using the Rest API. Im using powershell and am getting the below error:

 

Invoke-RestMethod : {"code":400,"message":"incomplete command","errorStack":[],"apiError":26214401}

 

here is my code:

 

$body = @{apiAnonymous = 'Redirect Traffic to 2 pools based on the URI
               when HTTP_REQUEST {

                       if {[string tolower [HTTP::uri]] contains "/1111/"} {
                            pool A
                       } else {
                       pool B
                       }
               '} | ConvertTo-Json


Invoke-RestMethod -Method PATCH -Uri "https://1.1.1.1/mgmt/tm/ltm/rule/~Partition~coolirule" -Credential $mycreds -body $body -ContentType "application/json"

The only information i can find on this suggests that i delete my iRule and create a new one.... i would like to try and avoid this if i can.

 

Regards Tim

    Most likely due to the special characters not escaped properly (depending on where you run) or LF (0x0A) not written in the literal \n (0x5C 0x6E) in a JSON body. The following curl request worked for me.

     cat sat
{
  "apiAnonymous":" this is a test\n
when CLIENT_ACCEPTED {\n
  log local0. \"Hello World\"\n
}"
}
 curl -sku admin:admin https:///mgmt/tm/ltm/rule/satoshi -X PATCH -H "Content-Type: application/json" -d@sat
{
    "apiAnonymous": " this is a test\nwhen CLIENT_ACCEPTED {\n  log local0. \"Hello World\"\n}",
    "fullPath": "satoshi",
    "generation": 986,
    "kind": "tm:ltm:rule:rulestate",
    "name": "satoshi",
    "selfLink": "https://localhost/mgmt/tm/ltm/rule/satoshi?ver=13.1.0"
}
