interaction.showModal not working

interaction.showModal doesnt work, I dont know why.
Code:

this.container.logger.debug("Start Editing...")
                const modal = new ModalBuilder().setTitle("Nachricht bearbeiten").setCustomId(`modal_edit_${swallowed.id}`)
                const input = new TextInputBuilder().setCustomId(`new_text`)
                    .setLabel("Text bearbeiten")
                    .setPlaceholder("Neuer Text")
                    .setValue(swallowed.message_content)
                    .setRequired(true)
                const actRow = new ActionRowBuilder<TextInputBuilder>().addComponents(input);
                modal.addComponents(actRow)
                this.container.logger.debug("Showing Modal...")
                await interaction.showModal(modal)```
Via the debug-commands, I found out, that only the last line throws the error.
It is something like: ```
2023-02-26 20:33:32 - ERROR - ValidationError > s.nativeEnum(T)
2023-02-26 20:33:32 - ERROR -   Expected the value to be a string or number

To be a little bit more concrete:

Nevermind missed an option in the Textinputbuilder. I am dumb.
