ERR_HTTP_INVALID_HEADER_VALUE in Version 2.3.3

[JD2k]

Hello,

on uploading a file in version 2.3.3. iam getting this error:

W20250205-17:19:45.483(1)? (STDERR) (node:69126) UnhandledPromiseRejectionWarning: TypeError [ERR_HTTP_INVALID_HEADER_VALUE] [ERR_HTTP_INVALID_HEADER_VALUE]: Invalid value "undefined" for header "Access-Control-Allow-Origin"

If i rollback to version 2.2.1 everything works fine. Can you help me out here?

Ostrio related code is not changed in both cases:

export const TenantFiles = new FilesCollection({
    collectionName: "TenantFiles",
    storagePath: tenantFilePath,
    allowClientCode: true, // Disallow remove files from Client
});

export const createUploadPromise = ({fileId, data, onProgress, callBackFunc}:
                                        {
                                            fileId?: string,
                                            data: File,
                                            onProgress?: (progress: number, file: File) => void,
                                            callBackFunc?: (upload: any, fileObj: any) => void
                                        }
) => {
    return new Promise((resolve, reject) => {
        const upload: FileUpload = TenantFiles.insert({
            fileId: fileId ?? undefined,
            file: data,
            chunkSize: "dynamic",
        }, false);
        upload.on("end", function (error: Error, fileObj: File) {
            //console.log('Upload end: ')
            if (error) {
                console.error(error)
                reject(typeof error === "object" ? {...error, ...fileObj} : error);
            } else {
                if (callBackFunc) callBackFunc(upload, fileObj);
                resolve(upload, fileObj);
            }
        });
        upload.on("progress", function (progress: number, fileObj: File) {
            if (onProgress) onProgress(progress, fileObj);
        });
        upload.on("error", function (error: Error, _fileObj: File) {
            console.error("Error during upload: " + error);
            reject(error);
        })
        upload.start();
    });
