The incoming YAML document exceeds the limit #1857

Closed skwashp closed 1 year ago

skwashp commented 1 year ago

As requested by @wing328 on OpenAPITools/openapi-generator/#14096, I am creating this ticket as it appears to be the right place to get it fixed.

Description

The generator fails wen using large spec files. Error: com.fasterxml.jackson.dataformat.yaml.JacksonYAMLParseException: The incoming YAML document exceeds the limit: 3145728 code points.

Suggest a fix

Implement a larger default or a configuration option so larger spec files can be used. @wing328 suggested an environment variable.

Yeah, the current limit fails parsing one of the Slack Swagger files

I'm facing the same issue

wtrocki commented 1 year ago

Problem can be patched by setting limits in following class https://github.com/swagger-api/swagger-parser/blob/06c86496875196667ed07abd1e8b42c53f06d4c3/modules/swagger-parser-v3/src/main/java/io/swagger/v3/parser/util/DeserializationUtils.java#L257-L263

Problem with adding this is that swagger parser is used in so many underlying projects that would need to expose this as some form of options or flags.
