Explanation

In verion 4.37.1 you have introduced a bug at:

tagify/src/tagify.js

Line 1081 in 37bf429

_s.dropdown.enabled = this.origSettings.dropdown.enabled;

When Tagify is instantiated without dropdown settings, and tagify.setReadonly(false) is called, then an error is thrown because this.origSettings.dropdown is undefined. (see jsbin above)

• What is the expected behavior?
  Should run without undefined error. If dropdown setting is omitted, fall back to default setting or include check if dropdown setting is provided.

• What is happening instead?
  Error is thrown.

• What error message are you getting?

Uncaught TypeError: Cannot read properties of undefined (reading 'enabled')
    at N.setReadonly (tagify@4.38.0:34:55046)
