When an account has the app search.resolver@1.x the sitemap can have errors when:

• A category has its first product coming from a similar category;
• The brand/category/department page has no products; in this case, the page is not indexed on the sitemap, and its generation crashes In both cases, the current page is not indexed in the sitemap, which usually leads to a sitemap without a brand, category, or department path.

Try to generate the sitemap for an account that has one of the scenarios described above and it will generate an incomplete sitemap.

• Create a new workspace
• Install the search-resolver@0.x (vtex install vtex.search-resolver@0.x)
• Generate the new sitemap
• Now you can rollback search-resolver to 1.x (vtex install vtex.search-resolver@1.x)
• Promote the created workspace to master

Stay in mind that updating the store to resolver@0.x and generating the sitemap in a workspace is the workaround because some invalid cases don't happen in our legacy search.
