[Question] Protocol error (Network.getResponseBody): No resource with given identifier foundError

[oleksii-hryhurko]

Hi i am trying to write something like network listener but sometimes i get this error, can you help me solve this problem:
Playwright v. 1.3.0
Code:
page.on('response', response => { if (response.url().endsWith('api/2/json')) { response.body().then(body => { console.log(response.request().postData()) console.log(res.toString()) }) } })
Stacktrace:
Protocol error (Network.getResponseBody): No resource with given identifier foundError: at node_modules/playwright/lib/chromium/crConnection.js:131:63 at CRSession.send (node_modules/playwright/lib/chromium/crConnection.js:130:16) at CRSession.send (node_modules/playwright/lib/helper.js:80:31) at Response.getResponseBody [as _getResponseBodyCallback] (node_modules/playwright/lib/chromium/crNetworkManager.js:218:49) at node_modules/playwright/lib/network.js:233:29

It might happen when the page navigates to a new url. We only allow fetching resource body while on the same page.
