What causes "error getting bucket: %#v" in hashicorp/terraform?

Correct the bucket name to lowercase letters, digits, and hyphens only (3-63 chars).

error getting bucket: %#v

Error message

error getting bucket: %#v

What it means

In RemoteClient.Put() (client.go:102-104), ossClient.Bucket(c.bucketName) failed. Like error 344, Bucket() is a local name-validation constructor; failure means the bucket name is invalid. This blocks every state write (terraform apply/refresh).

Solutions

Correct the bucket name to lowercase letters, digits, and hyphens only (3-63 chars).
Re-run terraform init after fixing the backend block so the client is rebuilt with the valid name.
Check the variable/local feeding bucket for stray characters or empty values.

Example fix

// before
backend "oss" {
  bucket = "TF_State_Bucket"
}

// after
backend "oss" {
  bucket = "tf-state-bucket"
}

Defensive patterns

Strategy: validation

Validate before calling

// Reuse the OSS bucket-name validator from error 344 before any Put path.
if !validBucketName(c.bucketName) {
    return fmt.Errorf("refusing Put: invalid bucket %q", c.bucketName)
}

Try / catch

// Local validation; not retryable. Fix the name and re-init.
if err != nil && strings.Contains(err.Error(), "error getting bucket") {
    return fixBucketName(err)
}

Prevention

Keep bucket names valid from day one; see error 344 validator.
Re-run terraform init whenever the backend block changes.
Lint backend config in CI.

When it happens

Trigger: Put() called during state persistence with a bucketName failing OSS naming rules (uppercase, underscore, bad length, illegal chars). No network call is attempted.

Common situations: Bucket attribute was changed to an invalid name after init; interpolation produced an invalid value; copy-paste of a non-normalized bucket name.
