APT repository InRelease files appear corrupted, gpp signature verification fails :

$ curl -s https://apt.releases.hashicorp.com/gpg | gpg --import
gpg: key AA16FCBCA621E701: public key “HashiCorp Security (HashiCorp Package Signing) security+packaging@hashicorp.com” imported

I can confirm this issue at least with respect to the jammy repo. The Release file is correctly signed by the Release.gpg file but the InRelease file that includes the Release file and the signature in the same file shows an invalid signature.
This was already acknowledged in the forum last year by @apparentlymart
Standard apt seems to work fine but mirroring systems like reprepro and debmirror fail.
Can this be checked?
