uninstall_post is not substituting %%%NAMESPACE%%%

[zenibako]

Describe the bug

When running the uninstall_post task, Salesforce throws an error UNKNOWN_EXCEPTION: Custom metadata type %%%NAMESPACE%%%[CUSTOM_METADATA_TYPE] is not available in this organization.

Presumably, this is because the uninstall_post task is not doing namespace replacements in package.xml or the metadata itself. Thedeploy_post task in the install_beta flow is successfully completing with the same unpackaged/post contents.

Samples below (brackets are used throughout for substitute text):

package.xml

...
    <types>
        <members>%%%NAMESPACE%%%[CUSTOM_METADATA_TYPE].[CUSTOM_METADATA_NAME]</members>
        <name>CustomMetadata</name>
    </types>
...

___NAMESPACE___[CUSTOM_METADATA_TYPE].[CUSTOM_METADATA_NAME].md

...
    <values>
        <field>%%%NAMESPACE%%%[FIELD_NAME]</field>
        <value xsi:type="xsd:string">[VALUE]</value>
    </values>
...

Reproduction steps

1. Create an unpackaged/post folder with metadata that requires namespace labels (such as custom metadata).
2. Run the deploy_post task on a non-namespaced org.
3. Confirm the uninstall_post task is configured with managed: True and your namespace.
4. Run the uninstall_post task on a non-namespaced org.

Thanks for the report and detailed instructions on how to reproduce the issue.

From initial inspection it looks like the problem is probably that the task is trying to replace ___NAMESPACE___ within package.xml instead of %%%NAMESPACE%%%. I've filed a bug W-10774453 in our internal tracker.

No problem! Thank you for the quick response.
