What was the cause of the issue? * Thread Starter [Zakir Sajib](https://wordpress.org/support/users/zakirstage/) * (@zakirstage) * [5 years, 3 months ago](https://wordpress.org/support/topic/workers-api-error-invalid_route_script_missing-err-code-10019/#post-14084908) * Sure. * There were 3 workers code existed before on same domain. And also later I understood api was accessing my account instead of my client account as I setup their cloudflare. Then I asked their password and get the api and then it works. * Now one issue. * What I notice home page first shows in browser console HIT in GET method but later in POST method it shows dynamic and the value: x-wp-cf-super-cache-worker- bypass-reason: caching not possible for req method POST * Please visit the site: [https://www.shopbylocals.com](https://www.shopbylocals.com). Use the network tab and in html tab , and load the site. * Plugin Contributor [iSaumya](https://wordpress.org/support/users/isaumya/) * (@isaumya) * [5 years, 3 months ago](https://wordpress.org/support/topic/workers-api-error-invalid_route_script_missing-err-code-10019/#post-14085014) * Hi [@zakirstage](https://wordpress.org/support/users/zakirstage/), Yes one specific route can be pointed to one worker only. * I visited the site and as I can see the caching is working perfectly. No issues. Only GET & HEAD requests are supposed to be cached. POST and other types of requests should never ever be cached by any system. * Thread Starter [Zakir Sajib](https://wordpress.org/support/users/zakirstage/) * (@zakirstage) * [5 years, 3 months ago](https://wordpress.org/support/topic/workers-api-error-invalid_route_script_missing-err-code-10019/#post-14085112) * ALright. * Another question: Is there any way I can merge your existing worker code? * for example this one: [https://gist.github.com/isaumya/c2667b737d4e1e48a8ebb0df24b89a39](https://gist.github.com/isaumya/c2667b737d4e1e48a8ebb0df24b89a39) * and this one too: * [https://github.com/pmeenan/cf-workers/tree/master/optimization-pack](https://github.com/pmeenan/cf-workers/tree/master/optimization-pack) * Or may be in your next update you can add the following feature: * Fast Google fonts and Third party Scripts. * Plugin Contributor [iSaumya](https://wordpress.org/support/users/isaumya/) * (@isaumya) * [5 years, 3 months ago](https://wordpress.org/support/topic/workers-api-error-invalid_route_script_missing-err-code-10019/#post-14085682) * Hi [@zakirstage](https://wordpress.org/support/users/zakirstage/), You definitely can. If you check the FAQ tab inside the plugin settings it is clearly mentioned how you can overwrite the existing worker code to add your own feature. So, you basically start with our code, read it, understand it and then add more features as you like it by overwriting the default worker script.
