No method named "${config}"

Error message

No method named "${config}"

What it means

Popover reuses Tooltip's method surface through class inheritance, and its jQueryInterface throws when the string is not found on the instance (simple undefined check). Public methods are show, hide, toggle, enable, disable, toggleEnabled, update, setContent and dispose. The content API added in 5.2 is setContent — updateContent does not exist.

Solutions

1. Use the inherited Tooltip methods: show, hide, toggle, enable, disable, toggleEnabled, update, setContent, dispose.
2. Replace 'destroy' with 'dispose' (v5 rename).
3. Use setContent({ '.popover-body': '...' }) for dynamic content, not updateContent.
4. Validate dynamic names against bootstrap.Popover.getInstance(el) before calling.

Example fix

// before
$('#pop').popover('updateContent', 'Hi') // TypeError: No method named "updateContent"

// after
$('#pop').popover('setContent', { '.popover-body': 'Hi' })

function callPopoverMethod(element, method, ...args) {
  const instance = bootstrap.Popover.getOrCreateInstance(element)
  if (typeof instance[method] !== 'function') {
    console.warn(`Popover: ignoring unknown method "${method}"`)
    return
  }
  instance[method](...args)
}

const POPOVER_METHODS = ['show', 'hide', 'toggle', 'enable', 'disable', 'toggleEnabled', 'update', 'setContent', 'dispose'] as const
type PopoverMethod = (typeof POPOVER_METHODS)[number]
const isPopoverMethod = (m: string): m is PopoverMethod =>
  (POPOVER_METHODS as readonly string[]).includes(m)

try {
  $('#pop').popover(method)
} catch (err) {
  if (err instanceof TypeError && err.message.startsWith('No method named')) {
    console.warn(`Popover: unknown method "${method}"`)
  } else {
    throw err
  }
}

When it happens

Trigger: $('#pop').popover('updateContent', {...}) — correct is setContent; $('#pop').popover('destroy') — v4 name, v5 is dispose; $('#pop').popover('open'); $('#pop').popover('setContentX').

Common situations: v4→v5 migrations ('destroy' → 'dispose'); developers guessing updateContent because setContent arrived mid-5.x; mixing Tooltip/Popover verbs with other UI libraries.
