Describe the bug

I am using HTTP node to genertate token to invoke my remote REST API
But when i configured HTTP node with Body type x-www-form-urlencoded and try to run WF gives error: 'invalid_request',

logs -

request: <ref *1> ClientRequest { _events: [Object: null prototype], _eventsCount: 7, _maxListeners: undefined, outputData: [], outputSize: 0, writable: true, destroyed: false, _last: true, chunkedEncoding: false, shouldKeepAlive: false, maxRequestsOnConnectionReached: false, _defaultKeepAlive: true, useChunkedEncodingByDefault: true, sendDate: false, _removedConnection: false, _removedContLen: false, _removedTE: false, strictContentLength: false, _contentLength: '11', _hasBody: true, _trailer: '', finished: true, _headerSent: true, _closed: false, _header: 'POST /sso/realms/example/protocol/openid-connect/token HTTP/1.1\r\n' + 'Accept: application/json, text/plain, */*\r\n' + 'Content-Type: application/x-www-form-urlencoded\r\n' + 'User-Agent: axios/1.7.9\r\n' + 'Content-Length: 11\r\n' + 'Accept-Encoding: gzip, compress, deflate, br\r\n' + 'Host: aiop-btms4.td.teradata.com\r\n' + 'Connection: close\r\n' + '\r\n', _keepAliveTimeout: 0, _onPendingData: [Function: nop], agent: [BoundHttpsProxyAgent], socketPath: undefined, method: 'POST', maxHeaderSize: undefined, insecureHTTPParser: undefined, joinDuplicateHeaders: undefined, path: '/sso/realms/example/protocol/openid-connect/token', _ended: true, res: [IncomingMessage], aborted: false, timeoutCb: null, upgradeOrConnect: false, parser: null, maxHeadersCount: null, reusedSocket: false, host: 'idp.example.com', protocol: 'https:', _redirectable: [Writable], [Symbol(shapeMode)]: false, [Symbol(kCapture)]: false, [Symbol(kBytesWritten)]: 0, [Symbol(kNeedDrain)]: false, [Symbol(corked)]: 0, [Symbol(kChunkedBuffer)]: [], [Symbol(kChunkedLength)]: 0, [Symbol(kSocket)]: [TLSSocket], [Symbol(kOutHeaders)]: [Object: null prototype], [Symbol(errored)]: null, [Symbol(kHighWaterMark)]: 65536, [Symbol(kRejectNonStandardBodyWrites)]: false, [Symbol(kUniqueHeaders)]: null }, data: { error: 'invalid_request', error_description: 'Missing form parameter: grant_type' } }, status: 400

To Reproduce

1. create new WF
2. add HTTP node
3. Method POST
4. URL - set URL
5. Header - Key=Content-Type , value=application/x-www-form-urlencoded
6. Body Type = x-www-form-urlencoded
7. set key values

Expected behavior

When i set Body type x-www-form-urlencoded, it should take configured body key value and execute request.
