I have a custom_object__c which has a lookup to Contact (Contact__c), I'm trying to pull the phone number on the contact and display it on my custom_object__c flexipage:

import { LightningElement, api } from 'lwc';

import NAME_FIELD from '@salesforce/schema/Custom_Object__c.Contact__r.Phone';
export default class MyComponent extends LightningElement {
    // Expose a field to make it available in the template
    nameField = NAME_FIELD;

    // Flexipage provides recordId and objectApiName
    @api recordId;
    @api objectApiName;

    content goes here:
    <lightning-record-view-form object-api-name={objectApiName} record-id={recordId}>
        <lightning-output-field field-name={nameField}> </lightning-output-field>

I'm getting the following error:

outputField.js:1 Error: Field [Contact__r.Phone] was not found
    at Object.N [as getUiField] (fieldUtils.js:1:2729)
    at J.updateFieldInfo (outputField.js:1:6886)
    at J.wireRecordUi (outputField.js:1:7376)
    at dr (aura_prod.js:13:34198)
    at s.<anonymous> (aura_prod.js:13:18101)
    at eval (recordViewForm.js:1:3841)
    at Array.forEach (<anonymous>)
    at pn.value [as forEach] (aura_prod.js:1:9281)
    at g.wireViewData (recordViewForm.js:1:3827)
    at g.handleData (recordViewForm.js:1:3154)

Is this a limitation of salesforce/schema/? I can't import related fields?

What are you trying to do will not work because Record View Form requires you to specify the information of the same object.

For example, if you include lightning-record-view-form on a record page for an account, set object-api-name="Account". If the record ID and object API name don't agree, the form doesn't display.

So in your case, the field and object-api-name will not match and it'll give you an error like the field doesn't exist, even after getting the schema of the field.

To get the field value from a parent record you can utilize two methods from Lightning data service - getRecord & getFieldValue.

You can refer below example -

import { LightningElement, api , wire} from 'lwc';
import CONPHONEFIELD from '@salesforce/schema/Custom_Object__c.Contact__r.Phone';

import { getRecord, getFieldValue } from 'lightning/uiRecordApi';

const fields=[CONPHONEFIELD];

export default class ParentRecordValue extends LightningElement {
    conPhone = CONPHONEFIELD;
    @api recordId;

    @wire(getRecord, { recordId: '$recordId', fields })
    record({ error, data }) {
        if (data) {
            console.log('contact phone ' + getFieldValue(data, this.conPhone));
