We are working on Odoo 19 (SaaS, Odoo Studio). After Studio customizations, a critical server error occurs when saving products (product.template): ValueError: Cannot convert product.template.product_variant_id to SQL because it is not stored The error persists even when: custom fields are removed from the views the default Odoo views are restored Objective Identify and correctly fix the exact technical root cause, so that: products can be saved without errors non-stored fields (store = False) are no longer used in domains, filters, related fields, automations, or ORM triggers Mandatory Working Rules NO trial-and-error NO random changes NO “quick fixes” NO changes without prior explanation and approval Every planned change must be explained first and approved by me before execution. Required Technical Investigation The freelancer must systematically inspect: Domains & Filters saved filters automatic search filters domains in views, fields, or actions Related Fields (Odoo Studio) especially chains involving product_variant_id or product_variant_ids any related field with store = False Computed Fields computed Studio fields fields indirectly used in SQL queries Automations Studio automations on-write / on-change triggers Orphaned Studio Fields fields no longer visible in views but still active internally Acceptance Criteria (Very Important) The task is considered complete only if: The exact root cause is clearly identified (e.g. Field X with Domain Y referencing non-stored Field Z) It is clearly explained why the error occurs even when the field is not visible in the form Products can be saved successfully without any server error Explicitly NOT Wanted rebuilding forms from scratch deleting elements “just to try” undocumented changes multiple changes at once without a clear explanation Effort & Payment Estimated effort: 1–3 hours Payment is based on proper analysis, not experimentation Required Profile Please apply only if you have: strong Odoo ORM knowledge (v16–v19) solid experience with Odoo Studio & ir.model.fields proven ability to perform systematic root-cause analysis If you want, I can also provide: a short version for Fiverr a screening checklist to evaluate the freelancer live or a step-by-step validation plan once someone starts Just tell me.
