Issue: Zephyr reporter fails with 401 after updating API token (Invalid JWT – 0 parts)

[Baskar5532]

Description

After updating to a new Zephyr API token, the Playwright Zephyr reporter fails to upload test results and returns a 401 Unauthorized error.
This happens even when the token is freshly generated and correctly configured.

Error Output
[zephyr reporter]: Failed to upload results. Error:
Status: 401
Headers: Object [AxiosHeaders] {
date: 'Wed, 21 Jan 2026 07:04:25 GMT',
'content-type': 'application/json',
'content-length': '63',
connection: 'keep-alive',
'strict-transport-security': 'max-age=31536000; includeSubDomains'
}
Data: { error: 'The token was expected to have 3 parts, but got 0.' }

Questions

Has the Zephyr API token format changed recently?

Is playwright-zephyr@1.1.0 compatible with the latest Zephyr Scale JWT format?

Are there additional headers or configuration required for new tokens?
