Openlayers geojsoncông việc

I need to create full screen map using nextjs and mapbox The map have to cover full screen When a user click on a point on the map, the application will request a GeoJson dataset of points. Although the GeoJSON requested will be a whole dataset, the application should only display the pins within a 1km radius of the clicked point. Of course, the 1km is not fixed. I need a slider component that the user can change the radius of the circle, instead of 1km fixed. In project, don't use any other material library. You need to use Radix UI for further integration. Because my prev guy said he used headless (I'm not sure) UI. Also, It should be responsive for mobile and tablet.

We have a script which converts an ArcGIS LYRX document into Geo Styler format. We then use geostyler plugin to load our style into openlayers. Our script was programmed to collect the data from .lyrx documents and convert them. The script worked great without any issues when loading directly from the document. We recently changed our app to load the lyrx data from our database. In this process we simply removed line returns and saved the data into the database. We then changed the function to accept a string from the database rather then read from the file. Once we did this it broke our labels and crashes our application. The basic style loads correctly and layers load correctly but labels cause the following javascript error. JavaScript Error: {"type":"&quo...

We are looking for someone to fix the formatting and get our layers to display correctly. If this is something you know you can do please submit a quote.
