JSON validation failed: File '/schema.ts' is not a module.\n'Object' only refers to a type, but is being used as a value here.\nCannot find name 'exports'

I'm using this function to get summary

export const  getSummary = async (mails:string) =>{
return new Promise(async (resolve,reject)=> {

       const response= await  translator.translate(mails);
       if (!response.success) {
           console.log(response);
           return reject(response);
    }
    const summarizedMail = response.data;
    console.log(JSON.stringify(summarizedMail,undefined, 2));
    if (summarizedMail.summaryObject.type==="unknown") {
        console.log("I didn't understand the following:");
            console.log(summarizedMail.summaryObject.text);
        
    }
    resolve(response)
})

Here's the schema file

export interface SummarizedMailItems {
    type:'mailSummary',
    summarizationLanguage: 'arabic' | 'english' | 'french' | 'spanish'
    summaryParagraph:string ,
    summaryBulletpoints: [string,string,string]
    
}

export interface UnknownText {
    type:'unknown',
    text: string; // The text that wasn't understood
}

export type SummarizedMail = {
    summaryObject: SummarizedMailItems | UnknownText;
};

I'm getting this error

{
  success: false,
  message: "JSON validation failed: File '/schema.ts' is not a module.\n'Object' only refers to a type, but is being used as a value here.\nCannot find name 'exports'.\n{\n  \"paragraphSummary\": \"..........",
}```

Start by reproducing the validation failure using the getSummary function and the schema.ts content shown in the issue. Inspect how the schema is loaded and validated, then determine why the exported interfaces produce module, Object, and exports errors. Done means the schema validates successfully and the summarized response can be processed without these errors.
