If you add a little bit more detail, it would be easier to help you.

  • In which doctype?
  • What exactly are you trying to add
  • Does this page have a webview? (had a similar error once because of that)
  • In which doctype? Sales invoice
  • What exactly are you trying to add - I try to add another doc type as a link type to sales invoice. this enable me to select from the doc list.
  • Does this page have a webview? No

This seems to be a Language setting or language translation lookup issue?

For the example case of Language set to ‘de’ (in System Settings) this (key, value) lookup succeeds, given this key:
“{0}: Options {1} must be the same as doctype name {2} for the field {3}”
the value for that key is this translation:
{0}: Die Optionen {1} müssen mit dem Doctype-Namen {2} für das Feld {3} identisch sein.

Here’s the grep code search for that:

(env) frappe@ubuntu:~/frappe-bench$ find . -name ‘de.csv’ | xargs grep “{0}: Options {1} must be the same as doctype name {2} for the field {3}”
./apps/frappe/frappe/translations/de.csv:apps/frappe/frappe/core/doctype/doctype/doctype.py,{0}: Options {1} must be the same as doctype name {2} for the field {3},{0}: Die Optionen {1} müssen mit dem Doctype-Namen {2} für das Feld {3} identisch sein.

In your System Settings, what is Language set to - say ‘si’ ??

If that’s the case, that lookup has no translation as this shows:

(env) frappe@ubuntu:~/frappe-bench$ find . -name ‘si.csv’ | xargs grep “{0}: Options {1} must be the same as doctype name {2} for the field {3}”
(env) frappe@ubuntu:~/frappe-bench$
