Hey folks, I am having a troubles with creating a string parameters. When I try to do so, it throws Error: Only NUMBER parameters are supported instantly. Am I doing something wrong ?

The issue is likely that string parameters are gated behind a feature flag that needs to be enabled first. According to the SDK, there is an

enableStringParameters

feature flag that controls authoring of string (textual) what-if parameters. [Feature Flags] String parameter support was also introduced as an experimental feature in late July 2026. [What's New] Here's what to check: 1. Ensure the

enableStringParameters

feature flag is enabled in your workspace/organization settings. Without it, only

NUMBER

parameters are supported in the catalog YAML editor, which would explain the error you're seeing. 2. Verify your YAML definition is correct. A valid string parameter definition looks like this🆔 scenario title: Scenario description: Controls which planning scenario is used in scenario-based metrics. definition: type: STRING defaultValue: Actual constraints: allowedValues: - Actual - Budget - Forecast tags: - Favorites[Create Parameters] 3. Check your GoodData version — string parameters require React SDK 11.49+ and Python SDK 1.71+. [What's New] If the feature flag is not yet enabled in your environment, you'll need to contact GoodData support or your administrator to have it turned on, as it is currently an experimental feature. 👍 0 button 👎 0 button ℹ️ Tip: Mention @kapa.ai in the thread for follow-ups. 👀 Our Support team monitors all messages and will jump in if needed.

While using your own example on the docs, I am getting this error now: - Favorites

Hi Jakub, looks like the remaining issue might be our documentation, not anything you did. The example on that page lists

allowedValues

as plain strings, but the editor expects each entry to be an object with a

value

key. This form should validate. Can you give it a try:

id: scenario
title: Scenario
description: Controls which planning scenario is used in scenario-based metrics.
definition:
  type: STRING
  defaultValue: Actual
  constraints:
    allowedValues:
      - value: Actual
      - value: Budget
      - value: Forecast
