DO access via env variables not works

[gelo22]

Problem: When DO access configured via env variables SPACES_SECRET_KEY and SPACES_ACCESS_TOKEN - I see error:

14:16:49 [DEBUG] Registering unit type: shell

for more information about providing credentials.

Error: failed to refresh cached credentials, no EC2 IMDS role found, operation error ec2imds: GetMetadata, access disabled to EC2 IMDS via client option, or "AWS_EC2_METADATA_DISABLED" environment variable

Configuration via yaml works as expected:

  access_key: "<SPACES_SECRET_KEY>"
  secret_key: "<SPACES_ACCESS_TOKEN>"

Source:

  access_key: "<SPACES_SECRET_KEY>" # Optional, it's better to use environment variable 'export SPACES_SECRET_KEY="key"'
  secret_key: "<SPACES_ACCESS_TOKEN>" # Optional, it's better to use environment variable 'export SPACES_ACCESS_TOKEN="token"'
