Issue with the implementation of a custom TextInput class

Hello, I'm trying to implement the following class in order to create a TextInputBuilder without having to use setPlaceholder, setCustomId, etc when creating a new object

interface TextInputProps {
  placeholder?: string;
  customId?: string;
  label?: string;
  style?: TextInputStyle;
  required?: boolean;
  minLength?: number;
  maxLength?: number;
}

class TextInput {

  private text: TextInputBuilder;

  constructor(props: TextInputProps) {
    this.text = new TextInputBuilder();
    this.setParameters(props);
  }

  public get(): TextInputBuilder {
    return this.text;
  }

  private setParameters(props: TextInputProps) {
    const functionsObject = {
      'placeholder': this.text.setPlaceholder,
      'customId': this.text.setCustomId,
      'label': this.text.setLabel,
      'style': this.text.setStyle,
      'required': this.text.setRequired,
      'minLength': this.text.setMinLength,
      'maxLength': this.text.setMaxLength,
    };

    for (const [key, value] of Object.entries(props)) {
      if (key && value) {
        console.log(`key: ${key}, value: ${value}`);
        functionsObject[key](value);
      }
    }
  }
}

interface TextInputProps {
  placeholder?: string;
  customId?: string;
  label?: string;
  style?: TextInputStyle;
  required?: boolean;
  minLength?: number;
  maxLength?: number;
}

class TextInput {

  private text: TextInputBuilder;

  constructor(props: TextInputProps) {
    this.text = new TextInputBuilder();
    this.setParameters(props);
  }

  public get(): TextInputBuilder {
    return this.text;
  }

  private setParameters(props: TextInputProps) {
    const functionsObject = {
      'placeholder': this.text.setPlaceholder,
      'customId': this.text.setCustomId,
      'label': this.text.setLabel,
      'style': this.text.setStyle,
      'required': this.text.setRequired,
      'minLength': this.text.setMinLength,
      'maxLength': this.text.setMaxLength,
    };

    for (const [key, value] of Object.entries(props)) {
      if (key && value) {
        console.log(`key: ${key}, value: ${value}`);
        functionsObject[key](value);
      }
    }
  }
}

However I'm receiving the following error:

key: placeholder, value: Product name
PROJECT_PATH/node_modules/@discordjs/builders/src/components/textInput/TextInput.ts:107
        this.data.placeholder = placeholderValidator.parse(placeholder);
            ^
TypeError: Cannot set properties of undefined (setting 'placeholder')

key: placeholder, value: Product name
PROJECT_PATH/node_modules/@discordjs/builders/src/components/textInput/TextInput.ts:107
        this.data.placeholder = placeholderValidator.parse(placeholder);
            ^
TypeError: Cannot set properties of undefined (setting 'placeholder')

Any idea?

Okay, thoughtless mistake: the functionsObject should receive a function with a parameter and return the setter from the discordjs TextInputBuilder class

'placeholder': (param: string) => this.text.setPlaceholder(param)

'placeholder': (param: string) => this.text.setPlaceholder(param)
