Pipe delimited content failing to be retrieved in a transform

[iamology (Nithesh Rao)]

Pipe “|” is a special character in Velocity which is causing the error. Here is a transform that returns a string @ index 0

{
    "name": "AATest_PipeCharacterInVelocity",
    "type": "static",
    "attributes": {
        "value": "$pipeString.split('\\|')[0]",
        "pipeString": "cddpo|St Joseph|Stp"
    },
    "internal": false
}
