/dashboard/export API compatibility issue between v1.5 and v2.0

[xingyc15]

We have some dashboard developed in v1.5.0. After we upgrade the dashboard into v2.0.0, and use the /dashboard/export API endpoint to export the dashboards, there are unreadable characters in the exported json file.

How to reproduce the bug

1. Develop a dashboard under superset version 1.5.0
2. Upgrade superset to version 2.0.0
3. Use /dashboard/export API to export the dashboard into a json file
4. See error

Expected results

The dashboard json exported from v1.5.0 should be able to be successfully parsed by superset v2.0.0

Actual results

There are some unreadable characters.

The json file starts with this:
PK!�gٝMM.dashboard_export_20220806T005733/metadata.yamlversion: 1.0.0 type: Dashboard timestamp: '2022-08-06T00:57:33.133934+00:00' PK!?�8���Fdashboard_export_20220806T005733/datasets/pinot/map_labeling_logs.yamltable_name: map_labeling_logs ...

Environment

• superset version: 1.5.0 and 2.0.0

Checklist

Make sure to follow these steps before submitting your issue - thank you!

• I have checked the superset logs for python stacktraces and included it here as text if there are any.
• I have reproduced the issue with at least the latest released version of superset.
• I have checked the issue tracker for the same issue and I haven't found one similar.

It is because in v2.0.0 dashboard is downloaded as zip file.
If you want to continue exporting dashboard as json file you need to add VERSIONED_EXPORT as False in FEATURE_FLAGS

FEATURE_FLAGS = {
        ...
        "VERSIONED_EXPORT": False,
    }

Any update about this bug?
If we use FEATURE_FLAGS = { ... "VERSIONED_EXPORT": False, } this condition will be always false
const canExport = hasPerm('can_export') && isFeatureEnabled(FeatureFlag.VERSIONED_EXPORT);

@Agos88 I think what you're talking about is a separate issue, and has been reported/is being tracked at #26417

I'm assuming that since this has been quiet for so long, we're all good now? VERSIONED_EXPORT has been deprecated, and we no longer support versions prior to 3.1/4.0. If this needs more discussion, we can certainly revisit/reopen.
