Error: request [/_transform] contains unrecognized parameter: [transformId]

[cwiechmann]

🐛 Bug Report

Javascript transform API is not accepting transformId even it's documented here: https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/8.0/api-reference.html#_transform_gettransform and was working well with version 7.x.y.
The same happens for all transform methods.

To Reproduce

Steps to reproduce the behavior:

The following code fails with the following error:

const client = new Client( { "some-elastic-config": "my-config" } );
client.transform.getTransform({ transformId: `myTransformId` });

Error:

ResponseError: illegal_argument_exception: [illegal_argument_exception] Reason: request [/_transform] contains unrecognized parameter: [transformId]

    at async putTransform (src\actions\transform.js:57:26)
    at async Object.method.action (src\index.js:659:19) {

Expected behavior

Using the parameter: transform_id it's working as expected. I expect the same behavior also when using transformId.

const client = new Client( { nodes: 'http://my-elasticsearch:9200'} );
client.transform.getTransform({ transform_id: `myTransformId` });

Your Environment

• node version: 12.13.0
• @elastic/elasticsearch version: >=@elastic/elasticsearch@8.0.0
• os: Windows
