Is it possible to filter items in data hub dialog?

[q-nicolechoi]

I want to filter the table of items in the data hub dialog. The docs suggest that I can use shouldIncludeFuncByItemType in the dialog, e.g.

workloadClient.client.datahub.openDialog({
    ...,
    supportedTypes: ['Lakehouse'],
    shouldIncludeFuncByItemType: {
        Lakehouse: (item) => {
            return true; // e.g. item.displayName.includes('abc') || !item.properties.defaultSchema
        }
    },
})

But I got an error in the console but I wasn't sure what really causes the error, or if this is the correct way at all to filter the table in data hub dialog. Has anyone been able to get this to work before?

ERROR DataCloneError: Failed to execute 'postMessage' on 'Window': item => {
          return true;
        } could not be cloned.

Hi Nicole,
The sample code has an example of filtering by type (where you select either Lakehouse or the SampleItem -

Microsoft-Fabric-workload-development-sample/Frontend/src/controller/SampleWorkloadController.ts

Line 295 in c59c0db

const datahubConfig: DatahubSelectorDialogConfig = {

Could you check if it works for you with the sample code, out of the box? Or try without the 'shouldIncludeFuncByItemType' value.
Do reach out if the issue persists.
Thanks!

Hi Vadim, originally we use the following and it works. It is when I try to filter the lakehouses using shouldIncludeFuncByItemType that gave me an error

const datahubConfig: DatahubSelectorDialogConfig = {
            supportedTypes: ['Lakehouse'],
            multiSelectionEnabled: false,
            dialogDescription: 'description',
            dialogAdditionalInfo: 'additional info',
            hostDetails: {
                experience: 'experience',
                scenario: 'scenario',
            },
            learnMorelink: {
                linkUrl: 'https://learn.microsoft.com/en-us/fabric/get-started/onelake-data-hub',
                linkText: 'Learn more about OneLake data hub'
            }
        };

Hi Nicole,

I can reproduce the issue on my side, and it appears to be a bug.

For now, this functionality is not supported. We will either fix it or remove it from the SDK.

Thanks,
Idan

Hi Idan,

It will be useful to know if this is supported in the long run, so once a decision has been made, would you mind coming back to this thread and give us an update please :)

Thank you,
Nicole
