   Here is my current workaround with an ensurePaths function:

   import {apply_patch} from 'jsonpatch';
   
   function ensurePaths(json: Record<string, unknown>, pathParts: string[]) {
     let current = json;
     for (let i = 0; i < pathParts.length - 1; i++) {
       const part = pathParts[i];
       if (part) {
         if (!current[part]) {
           current[part] = {};
         }
         current = current[part] as Record<string, unknown>;
       }
     }
   }
   
   export function setJsonValue(json: Record<string, unknown>, jsonPatchPath: string, value: string) {
     const pathParts = jsonPatchPath.split('/').slice(1);
     ensurePaths(json, pathParts);
     try {
       return apply_patch(json, [{op: 'replace', path: jsonPatchPath, value}]);
     } catch (error) {
       // Catch "Replace operation must point to an existing value!"
       return apply_patch(json, [{op: 'add', path: jsonPatchPath, value}]);
     }
   }

   I could improve the error handling if #41 gets implemented.
