Strange basic auth behaviour in 2026.1.2
We are using Yaak to successfully work with a public API. One end point redirects to Amazon s3 after auth to return a file and this now fails. It did work in 2026.1.1
I do not know if it is related to another issue we have with Yaak and authentication on this API. It authenticates on Basic auth with the api key going in the username field and a blank password field (eg ‘apikey:’). When creating a new request in Yaak it will never work first time until you have either entered and removed text in the password field for Basic auth or set an env in there such as PASSWORD and left the value blank in Environment variables.
Curl requests copied out from these broken Yaak requests match identically those that work and if imported also require manipulation of the password field/textbox. Duplicated requests within Yaak work first time.
Correction, it last worked in 2025.10.0-beta.1 on Mac OS x64 Sequoia
I cannot test versions between that and 2026.1.1 (fail to run) and it does not work in 1.2 and 2.0 beta.
Thanks for this detail! Taking a look at this now
Can you see if it works in the latest beta?

Thank you for this, it did fix the odd password field issue. Our issue with the redirect within the api request persists within these newer versions.
We are interacting with a UK Government API that redirects to an AWS S3 endpoint when requesting a file (pdf). AWS rejects it with: “Only one auth mechanism allowed; only the X-Amz-Algorithm query parameter, Signature query string parameter or the Authorization header should be specified”. It’s the companies house API if you want to test it - free to sign up to.
Is Yaak taking control of that redirect and passing basic auth on? Calling the AWS endpoint without base auth returns an expected expired result, but calling with base auth added returns error as above.
Thanks!
Can you try again with the latest beta? There was an issue with the redirect logic header forwarding

All working now, thank you so much.
Awesome, glad to hear it!
