DevTools failed to load source map: Could not load content for chrome-extension

[chojnicki]

About

Extension works fine (I can see queries, schema etc) but everytime in console I have warning:

DevTools failed to load source map: Could not load content for chrome-extension://mcfphkbpmkbeofnkjehahlmidmceblmm/content_script.js.map: HTTP error: status code 404, net::ERR_UNKNOWN_URL_SCHEME

What's even worse, it's on any page, not just Graphql. So it's not related to NPM package.

Reproduction

Just open DevTools (F12) on any site, and warning appears in console.

Expected result

No warning.

Actual result

Warning described before.

Additional info

environment	version
browser	Chrome 96 and Chrome 97 Beta
os	Linux Mint 20.2
urql	2.1.3
urql devtools	2.6.2
@urql/devtools	2.0.3

Edit: I can see now that there is one newer version (2.6.3) while on Chrome store it's 2.6.2. Why? Maybe update would help (even that I do not see anything related in changelog).
