Research direction
Reproduce the issue with the openapi-generator generate -i x.yaml -g typescript-axios -o ./src command, then inspect the typescript-axios generator templates and configuration for COLLECTION_FORMATS.pipe. Done means generated code no longer references a nonexistent member while still supporting pipe-delimited parameters; the issue names no test or source file to run.
