Update Variant Metafield on a Bundle Product

Shopify Plus

Topic summary

Main issue: A Shopify Flow that updates a variant metafield on inventory change does not trigger for Bundle products, though a similar flow on product creation works for Bundles and all flows work for standalone products.

What works vs. fails:

  • Works: On product creation, variant metafields are set correctly for Bundle products; inventory-change flows work for standalone products.
  • Fails: The inventory-change-triggered flow does not run for a Bundle product when inventory of one of its component items is updated.

Context/artefacts:

  • Screenshot of the flow was shared (image link) due to forum upload limits for .flow files.
  • A Loom video walkthrough demonstrates that updating a component’s inventory does not trigger the Bundle variant’s metafield update.

Requests and follow-ups:

  • A responder asked to review workflow runs; OP provided the video instead.
  • Another participant reported the same issue and asked if a solution exists.

Status:

  • No confirmed solution or workaround in the thread; issue remains open and reproducible for at least two users.

I have some flows setup to track inventory on variant metafields upon product variant creation and when inventory changes. Upon product creation, this works for Bundle products, but the flow that updates the variant metafield when inventory changes doesn’t run on the bundle product. Any help would be appreciated!

For some reason, this forum only allows me to attach .flow or .csv files, but gives me an error whenever I try to make a post with a .flow file attached, so I’ve linked to a screenshot of the flow instead of attaching it.

Variant Inventory to Metafield on Update is the flow that doesn’t work for Bundled products:

Note that the top 3 rows of logic are for standalone products and work fine, the bottom row is the issue.

Thank you.

What is the issue? Can you look at the workflow run and share that?

Hi Paul,

Thank you for your response.

I’ve recorded a screen share here explaining the issue as I think that will be faster than me trying to explain it over text: https://www.loom.com/share/699868c14346466d809c0d4a0f1931a0

To summarize, the flow does not trigger on the Bundle product when updating one of it’s components.
