How to accept .psd, .avi, .mov files in nestjs file interceptor?

Question

I am trying to accept multiple images in my request body, The files I am having problems are .mov, .psd, .avi.

This is my current code snippet

@UseInterceptors(FilesInterceptor('upload_image', 10))
  async uploadImage(
    @UploadedFiles(
      new ParseFilePipe({
        validators: [
          new FileTypeValidator({
            fileType: '.(png|jpeg|jpg|pdf|gif|svg|mp4|psd|bmp|mov|avi)',
          }),
          new MaxFileSizeValidator({ maxSize: 1024 * 1024 * 4 }),
        ],
      }),
    )
    files,
    @Body() body: UploadFileDto,
    @Req() req,
    @Res() res,
  ) {
// Some service logic
}

Iam getting the below response after selecting .avi , .mov, .psd files

{
    "statusCode": 400,
    "message": "Validation failed (expected type is .(png|jpeg|jpg|pdf|gif|svg|mp4|psd|bmp|mov|avi))",
    "error": "Bad Request"
}

It accepts file for evry other format other than the formats mentioned above.

Try adding mimeType as well. May be its throwing as mimeType is not mentioned. Refer this piece of code fileType: '^.*.(mov|quicktime|photoshop)$',
