openapi validation question

hi i am trying to validate an openapi 3 file, json format,

using other tools i got
{"errors":[{"code":400,"message":"Malformed OAS3 document: attribute components.schemas.Schema name ResponsePayloadByte[] doesn't adhere to regular expression ^[a-zA-Z0-9\.\-_]+$"}

and also this stuff
https://quobix.com/vacuum/
return some validation error.

if i try using openapi-parser lib inside a java app, i don't get any validation error, the file is correctly parsed and it work fine.

am i missing anything? shouldn't it fail?

i am attaching file that give error

thanks

PFM_User_Dots.json

首先，使用 openapi-parser 重現對所附 PFM_User_Dots.json 的驗證，並將其結果與其他已回報工具的結果進行比較。檢查 OpenAPI 3 的 schema 名稱限制，並判定 parser 是否應拒絕 ResponsePayloadByte[]；完成的標準是解釋這項差異，或記錄一個已確認的驗證缺陷。
