Hello, I want to automate the Katecorgi metafields by writing a product description, and then I want the system to extract the values for the metafields from the description. I keep geting errors. [Skärmavbild 2025-04-23 kl. 15.40.49.png]

It’s not clear what you want to do here and why you’ve left the value field empty when updating a metafield.

I want to write a product description. For example: Technical details Glass: Mineral glass When the system detects the value ‘Mineral glass’ in the description, I want it to automatically extract that value and place it in the metafield for ‘type of glass’.

thanks for the help but i still get some errors. I tried with the metaobjectupdate and got this errors "Mutation had errors: “Variable $id of type ID! was provided invalid value”, “Variable $metaobject of type MetaobjectUpdateInput! was provided invalid value” { “query”: “mutation metaobjectUpdate(…

It appears you are including fields that you really don’t need to update so it’s not clear which field this error is complaining about. Assuming that it’s they value field for your metaobject, you need to share more details about your metafield, specifically the types of each field.
