Unable to generate image via dalle using modelspec after updating to 0.7.5

[nathanwong91]

What happened?

While being on 0.7.5-rc1 we have been using modelspecs to give users an option for image generation. Here's the config we've been using

- name: "Generate Images using DALLE3"
  label: "Image Generation Tool (DALLE3)"
  description: "Generate images using DALLE3"
  preset:
    default: false
    endpoint: "gptPlugins"
    model: "gpt-4o"
    modelLabel: "Image Generation"
    tools: ["dalle"]
    greeting: |
      This assistant will generate images based on your query using DALLE3
    promptPrefix: |
      Taking the users input, generate an image using dalle3

Since moving to 0.7.5 this is now broken. We see an error in the logs

error: [PluginsClient] executorCall error: Cannot read properties of null (reading 'call')

and this error from the UI

Something went wrong. Here's the specific error message we encountered: Encountered an error while attempting to respond: Cannot read properties of null (reading 'call')

Another issue we've seen is the models are no longer selected properly

Even though we've set the following

    modelSpecs:
      enforce: true
      prioritize: true
      list:
        - name: "GPT4"
          label: "Basic (GPT4)"
          description: "Assist users"
          preset:
            default: true
            endpoint: "azureOpenAI"
            model: "gpt-4o"
            ~~~

I don't see anything in the changelogs to reflect changes to do with modelspecs other than labels

Steps to Reproduce

1. Setup ModelSpecs dalle on 0.7.5-rc1
2. Update to 0.7.5 without changing configuration
3. Ask it to generate an image

Add this:

          agentOptions:
            model: "gpt-4o"

      - name: "Generate Images using DALLE3"
        label: "Image Generation Tool (DALLE3)"
        description: "Generate images using DALLE3"
        preset:
          default: false
          endpoint: "gptPlugins"
          model: "gpt-4o"
          modelLabel: "Image Generation"
          tools: ["dalle"]
          agentOptions:
            model: "gpt-4o"
          greeting: |
            This assistant will generate images based on your query using DALLE3
          promptPrefix: |
            Taking the users input, generate an image using dalle

Note: plugins will be deprecated soon in favor of a better system: #3607

@danny-avila : Is it is compulsory to use ModelSpec within the librechat.yaml config file for 0.7.5 version? We are not using ModelSpec, Still we are facing same Issue. please suggest
