To Reproduce

part yaml

No response

Relevant log output

We can do a client side check for the expiration date to provide a potentially better error message

cat exported.creds |  base64 -d | jq '.v' -r | base64 -d

@sergiusens
I tried to simulate this error in mac os.

Time i choosed is 2 mins to expire login.
If i understand correctly macaroon is login expire time.

snapcraft export-login --expires "2023-08-22T14:38:00Z" exported.creds
export SNAPCRAFT_STORE_CREDENTIALS=$(cat exported.creds)

Here is error i got.

craft-store error: Store operation failed:

• macaroon-authorization-required: The request is missing an Authorization header field containing a valid macaroon
