Getting "Request failed with status code 400" when adding no SSH key in keystore

When I try to add a new SSH key in the keystore, I get a "Request failed with status code 400" erro and level=error msg="illegal base64 data at input byte 4" in the logs.

have you populated SEMAPHORE_ACCESS_KEY_ENCRYPTION with a valid key?
