Solution

Offline environment

If you are using an offline environment, use the following steps.

1. Get sourcePackageName and sourcePackageVersion from the imported model's metadata.json file.
2. Upload an out of the box ML Package (bundle) using the same name and version if it exists.
3. Export the ML Package.

Note: If there is no package with the same name and version in the destination environment, try using an online envirnoment.

Online environment

If you are using an offline environment, use the following steps.

1. Go to the ML Packages page.
2. Select UiPath Document Understanding if it's a Document Understanding model.
3. Select ML Package by sourcePackageName (Invoices, for example).
4. Use the version of the latest ML Package and update the same version in the metadata.json file.

Note: Make sure that once imported, languageVersion and the language of the imported version is the same as the one mentioned in the import package's metadata.json file. If the version is not the same, run the following query:

update [ml_package_versions] set language_version =<import_package_metadata's_language_version>
and set ml_package_language =<import_package_metadata's_ml_package_language>
where id =<imported_package_id>
