error parsing template %q: %v

Error message

error parsing template %q: %v

What it means

The Go text/template definition passed to newTemplateResource failed to parse. This is a developer-facing error: the embedded template source (keyed by the name in the message) contains a syntax error such as an unmatched delimiter or bad function call.
