How can I pass JSON data to a webhook Chainlink job?

I am trying to get the "Pipeline Input" to somehow be passed to an external adapter via the $(jobRun.requestBody) pipeline variable and then parsed by a jsonparse task and then sent via a fetch task. I am not sure what format the input should be in when running a webhook job on a Chainlink node. I keep getting this and other errors no matter what I try:

data: key requestBody (segment 1 in keypath jobRun.requestBody): keypath not found

This is what I am seeing on the Chainlink Admin UI: enter image description here

Here is the closest thing I have found in the documentation:
- https://docs.chain.link/chainlink-nodes/oracle-jobs/job-types/webhook

Here is the job definition if useful:

type = "webhook"
schemaVersion = 1
name = "account-balance-webhook"
forwardingAllowed = false
observationSource = """
parse_request  [type="jsonparse" path="data,address" data="$(jobRun.requestBody)"]
fetch        [type=bridge name="test" requestData="{\\"id\\": \\"0\\", \\"data\\": { \\"address\\": \\"$(parse_request)\\"}}"]
parse        [type=jsonparse path="data,free" data="$(fetch)"]

    parse_request -> fetch -> parse
"""

I am running Chainlink in a Docker container with this image: smartcontract/chainlink:1.11.0-root

Some background: I am working on developing an external adapter and want to be able to easily and quickly test.

We use the following webhook job to quickly verify there is no syntax errors, etc. with the bridge to an EA.

type            = "webhook"
schemaVersion   = 1
name = "[WH-username] cbor0-v0"
observationSource   = """
    fetch [type="bridge" name="bridge_name" requestData="{ \\"id\\": $(jobSpec.externalJobID), \\"input1\\": \\"value1\\" }"]
    parse [type=jsonparse path="data,results" data="$(fetch)"]

    fetch -> parse
"""

In general, its best to quickly test an EA directly through curl GET/POST. If the curl works, then a bridge will work as long as you named the bridge correctly in the job-spec.toml
