fix(migration): pm sendrequest without blockstatement

[abhishekp-bruno]

BRU-4292
( Should be merged after #9162 )

Description

When importing from postman if we a script when has a callback without block statement
like this : pm.sendRequest({ url: 'https://x' }, (err, res) => console.log(res.code));
then that block of the script gets passed completely unchanged to bruno.

Problem

In the current implementation we rebuild all the callbacks once the response handling is completed using this codeblock

j.functionExpression(
    null,
    [j.identifier(errorVarName), j.identifier(responseVarName)],
    j.blockStatement(callbackBody.body)
  );

now if there is no BlockStatement in a function i.e. {...} then callbackBody.body becomes undefined and this part of the conversion fails.

Fix

Before creating and returning the full callback we just check if there is a blockstatement or not and if not we just return the callback as it is

  if (callbackBody.type !== 'BlockStatement') return callback;

Walkthrough

The pm.sendRequest transformer now processes callbacks through AST paths, preserves callback shapes, rewrites response access, and marks callbacks async. Tests cover concise and block-body arrow callbacks.

Changes

sendRequest callback translation

Layer / File(s)	Summary
Callback transformation and response rewriting packages/bruno-converters/src/utils/send-request-transformer.js	Callback processing now uses the call path, rewrites response access through a generalized helper, preserves callback structure, and handles promise-chain handlers with explicit response parameters.
Arrow callback translation tests packages/bruno-converters/tests/postman/postman-translations/transpiler-tests/transformers/send-request.test.js	Expectations now cover callback formatting and concise arrow callbacks, including response methods, object bodies, error-only parameters, and block bodies.

Error-handling callbacks can have altered property access; guard rewriting on a second response parameter before merging.

🟡 Minor · Skip response-access rewriting without a second identifier parameter. · packages/bruno-converters/src/utils/send-request-transformer.js:395-405

395-405: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Skip response-access rewriting without a second identifier parameter. transformCallback defaults to response when params[1] is absent. Under the (error, response) callback contract, a one-parameter callback named response receives the error. The current code can therefore translate response.code to response.status, changing error-handling behavior. Run rewriteResponseAccess only when params[1] is an identifier.
