Team name '$teamName' does not match $teamNameRegex.

Error message

Team name '$teamName' does not match $teamNameRegex.

What it means

Team/owner names in BotMaker configs must match teamNameRegex, defined as ^[a-z][a-z0-9\-]*$ (lowercase, may contain digits and hyphens, must start with a lowercase letter). validateTeamName throws ConfigFailure for any team string violating this.

Solutions

1. Use the lowercase hyphenated team slug, e.g. "content-trust"
2. Pull from a canonical team registry rather than free-typing the name
3. Validate the team field at config authoring time (lint rule)

Example fix

// before
team("Content Integrity Team")

// after
team("content-integrity")

TEAM_RE = re.compile(r'^[a-z][a-z0-9\-]*$')
def validTeam(t): return bool(TEAM_RE.match(t))

def isValidTeam(name: str) -> bool:
    return bool(re.match(r'^[a-z][a-z0-9\-]*$', name))

When it happens

Trigger: Setting the owning team to a value that is not lowercase-leading — e.g. "ContentTeam", "_infra", "trust & safety", or empty string.

Common situations: Using team display names or LDAP group names with spaces/uppercase instead of the lowercase slug; migrating configs where the team field was optional and left blank.
