Trouble getting URL parameters

[tag]

I'm having trouble to access URL parameters.

I have followed both guides:

Defining and Using URL Parameters

Intro With Wappler you can access the values of your URL Parameters.

Filtering Database Query with an URL Parameter

If you don’t know how to define an URL parameter on your page, please check this tutorial as you will need this later. First, we need to create a server action. Open the server connect panel and click the add new button: [image] We call it product_details: [image] Then right click GET under Globals menu: [image] Add variable: [image] This variable will be used to filter our database query.

"BaseComponent.js:301 Unknown component found! query-manager"

my target is a node+ docker deployment

any suggestions?

Hi. Welcome to the community.

Based on the error, it seems you have not saved the layout page.
Whenever you add a new type of component in any of the content pages in NodeJS, Wappler automatically added required JS/CSS files in the layout page associated with that content page.

Either you are missing the layout page, which means there is an issue with the project setup itself.
Else, you should see that there are unsaved changes in layout page. Just save that and try again.
