Cannot select product in child table inside CRM Deal (Frappe Portal)

Hi all,

I’m using the standard CRM module in Frappe and encountering an issue when accessing a Deal through the CRM Portal.

Problem:

In the “Data” tab of the Deal, there’s a table for products. When I try to add a new row and select a product, the Link field doesn’t work — no dropdown appears, and I cannot select a product.

Because of this, I’m unable to complete or save the Deal from the portal. When I try, I get the following error:

Error: /api/method/frappe.client.set_value MandatoryError

Notes:

  • This is happening only on the Portal (not in the Desk).

Any suggestions for this problem?

My Environment:

  • Frappe CRM: v1.48.2 (main)
  • Frappe Framework: v15.72.3 (version-15)
  • Frappe WhatsApp: v1.0.7 (master)
