Trouble publishing terraform provider

We have been trying to publish our terraform provider on the terraform registry using the tutorial instructions provided by HashiCorp. Everything seems to be done correctly, yet we keep getting cryptic error messages by the publisher on the TF Registry website (e.g. missing release asset for [“terraform-provider-coxedge_v0.2.4_manifest.json”]). If anyone could steer us in the right direction we would be most grateful!
