Update issue with $set and dot notation

[harry-73]

Hi,

I have an issue when i try to update via $set and the dot notation. If i put {skipSchema: true}, the update is done without problem.
the problem is present for releases 1.0.9/zod 3.x and 2.0.0/zod 3.x or 4.x .

Thanks.

The schema is the following:

const activityGpxSchema = z
  .object({
    GPX: z.object({
      type: z.string(),
      features: z.array(
         z.object({
            type: z.string(),
            properties: z.object({
               time: z.string(),
               coordinateProperties: z.object({
                  times: z.array(z.string()),
                  heart: z.array(z.number()),
                  segments: z.array(
                     z.object({
                        index: z.number(),
                        highway: z.string().nullable(),
                        surface: z.string().nullable(),
                        tracktype: z.string().nullable(),
                        smoothness: z.string().nullable(),
                    })
                  )
                  .optional(),
               }),
            }),
            geometry: z.object({
               type: z.string(),
               coordinates: z.array(z.array(z.number())),
            }),
         })
      ),
    }),
    isCorrectGpx: z.boolean(),
 })

The update code:

   await ActivitiesGPX.updateAsync(
              { _id: id },
              {
                $set: {
                  'GPX.features.0.geometry.coordinates': time_gps_data,
                  isCorrectGpx: true,
                },
              }
            );
          } catch (error) {
            console.error(
              '[updatePolylineCorrectGpsActivityGpx] - error: ',
              error
            );
          }

The error.

Hi Stephan,

Thanks for reporting this issue. I just published a new version 2.0.1 which solves it, added a test with your case and made v2 backwards compatible with zod v3.

Please reopen the issue if this does not resolve your problem.

Thanks for your feedback.

Unfortunately, it does not solve my issue. I look deeper and the exception is raised when the code goes to line 293 (same with 2.0.0/zod 4.1.5)

zod-schema/src/extendWithSchema.js

Line 293 in 4ae86ad

const newValue = schemaToCheck.parse(args[1][key]);

PS: I am not allowed to reopen the issue.

@harry-73 can you provide a reproduction repo please. I was not able to reproduce it, the test I added is the exact use case you provided. Maybe im missing something that can be catched with a reproduction.
