mmm my investigations show that the problem lies when using Undici@7 (as
bundled in Node 26) with a Undici@8 in the tests. In this circumstance, the
interceptor's `body` matching fails e.g.
```js
test('should be able to send replication request with local database names -
POST /_replicate - nano.db.replicate', async () => {
// mocks
mockPool.intercept({
method: 'post',
path: '/_replicate'
//body: JSON.stringify({ source: COUCH_URL + '/source', target:
COUCH_URL + '/target' })
}).reply(200, response, JSON_HEADERS)
// test POST /_replicate
const p = await nano.db.replicate('source', 'target')
assert.deepEqual(p, response)
mockAgent.assertNoPendingInterceptors()
})
```
- if I comment out body matching, the test works
- if I uncomment it the test fails with `Error: error happened in your
connection. Reason: MockNotMatchedError: Mock dispatch not matched for body
'[object AsyncGenerator]' on path '/_replicate': subsequent request to origin
http://127.0.0.1:5984 was not allowed (net.connect disabled), 1 interceptor(s)
remaining out of 1 defined`.
I don't really want to comment out all the body values because then I'm not
testing whether Nano is sending the correct data!
So perhaps we park migration to Undici@8 for the moment :)
