Error when selecting model for Agent Builder

[swiftdev29]

What happened?

Tried creating an agent using agent builder, LC instance is hosted on HF, all models are modelspec-ed with a custom provider. When i try to select the model and provider for the agent and then click the “back” button, to go back to the agent builder I get the error pasted below. This makes creating agents impossible. Tried on multiple devices/browsers

Steps to Reproduce

1. Create an Agent using Agent Builder
2. Use any model defined as a Model Spec ( i am not sure if it occurs for default models as well)
3. Clicking the back button arrow results in error

What browsers are you seeing the problem on?

More details are required.

What are your modelSpecs configured like? (bare minimum reproduction)

What endpoints are selected for those modelSpecs? What is the list of available models for those endpoints?

Sample of one of the ModelSpec. enforce+prioritize = true

  - name: "Instant-EP"
    label: "Instant"
    description: "Quickest model"
    preset:
      default: true
      endpoint: "myEP"
      model: "gpt-4o-mini"
      temperature: 0.90
      modelLabel: "Instant"
