# There is an error in ModalSubmitInteraction.js

[KasaiKonoru]

Which package is this bug report for?

discord.js

Issue description

Always get the MODAL_SUBMIT_INTERACTION_FIELD_NOT_FOUND error because of this failure in code:
interaction.fields.getField() never got the custom ID of the field

discord.js/src/structures/ModalSubmitInteraction.js

Line 93 in cb11c56

customId: c.custom_id,

"c.custom_id" needs to be "c.customId"
Now TextInputComponent() and getField() get the customId again!

Code sample

static transformComponent(rawComponent) {     
return rawComponent.components.map(c => ({       
value: c.value,       
type: MessageComponentTypes[c.type],       
customId: c.customId, // << was c.custom_id before     })); 
}
//Now TextInputComponent() and getField() get the customId again!

I cannot reproduce this issue. My code sample is actually simply copied from the version 13 guide.

Moreover, this seems to be impossible. This method is referenced in one place only:

discord.js/src/structures/ModalSubmitInteraction.js

Lines 37 to 45 in cb11c56

	/**
	* The inputs within the modal
	* @type {PartialModalActionRow[]}
	*/
	this.components =
	data.data.components?.map(c => ({
	type: MessageComponentTypes[c.type],
	components: ModalSubmitInteraction.transformComponent(c),
	})) ?? [];

c is raw data, so custom_id is the correct property to use.

The more likely scenario is you are doing something incorrectly or the internal behaviour of discord.js has been edited (especially since this has not changed since implementation and no one has complained).

ok thanks. But many people in the discord server have this issue. I reinstalled discord v13 and used a new bot with the guide copied and pasted. But I always get the same error

[KasaiKonoru]

the textinput was only logged without error when I modified c.custom_id to c.customId

But many people in the discord server have this issue.

I have a hard time believing that, considering modal support was added over a year ago, I cannot reproduce this, and this code has been untouched. Care to link these many people in the server?

From Discord, it was found that the reporter had a third-party package installed which modified the internal behaviour of discord.js resulting in this error (posting for transparency).
