Data Architect

Facing issue in R Shiny app for downloading email attachments.

So I am a data analyst and recently I am working on automating the task of downloading email attachments (po, grn etc pdfs). I am using R Shiny for it, where I have created an app like interface. I am using the API for accessing Gmail. I have enabled the API, correctly configured the OAuth consent screen, defined all the scopes in the code, my authentication is also successfully happening by going on the web but still my code is not able to fetch any mail data. I am getting the forbidden:http (403).

Today I found out about China's teardown and reverse engineering culture

If you look through recent headlines and viral tech forums, you can't miss the flood of teardown analysis reports being shared and dissected. Companies like TechInsights, Munro & Associates, iFixit, MarkLines, and even specialist Chinese platforms such as 52audio and Chongdiantou are producing deep, detailed reports that tear open the most hyped products—think iPhones, Teslas, Huawei Mate phones, or Xiaomi EVs—revealing their inner secrets for everyone to study. These teardowns aren't just about satisfying geek curiosity (though, let's admit, that’s a huge part—they're the ultimate engineering ASMR!). They're about unleashing a wave of competitive research, strategic sourcing, and hands-on education that's changing industries. China has transformed teardown analysis and reverse engineering from niche industry practice into a comprehensive national strategy embedded across manufacturing, R&D, and industrial policy. Major Chinese Teardown Platforms & Reports: 1) 52audio (我爱音频网): Over 365 teardown reports on audio products, smartwatches, wearables; comprehensive TWS earphone ecosystem analysis 2) Chongdiantou (充电头网): Specializes in GaN chargers, power stations, charging technology teardowns 3) MarkLines China: Automotive EV teardowns including BYD, Xiaomi SU7, Tesla analysis China's Strategic Reverse Engineering 1) Success Stories:High-Speed Rail (HSR): Reverse-engineered foreign rail technology, now world leader with 11,000+ km of track and global exports 2) Aerospace: Systematic reverse engineering of Soviet, European, American aircraft designs (J-11, J-15, J-16, J-20, J-35) 3) Semiconductors: Despite sanctions, achieved 7nm chip manufacturing through systematic teardown and reverse engineering efforts 4) EV Technology: BYD, Xiaomi leveraging teardown insights to create competitive domestic platforms What’s Inside a Viral Teardown Report? Imagine a document packed with: High-resolution photos of every layer, chip, and connector.Circuit diagrams painstakingly reconstructed from physical parts. Bills of materials (BoMs) and supplier lists—sometimes tracking origins to single factories. Physical measurements, manufacturing techniques, cost modeling, and even step-by-step chip microscopy.For example, the TechInsights teardown of the Huawei Mate 60 Pro dropped like a bombshell by exposing China’s 7nm chip manufacturing breakthrough, directly challenging western tech sanctions. Similarly, Munro’s Tesla Cybertruck teardown made waves by revealing its gigacast frame and unique motor architecture—raising alarms and ambitions among rival automakers. How Can India Do It? Set Up Dedicated Teardown Labs: Use multidisciplinary teams to reverse engineer hot products across electronics, automotive, telecom, and energy sectors. Leverage Local Manufacturing Relationships: India’s position in global supply chains (think smartphone assembly, auto components) can be turned into unique teardown research opportunities. Document and Share: Build open-access repositories (think Indian iFixit or TechInsights) to democratize and crowdsource reverse engineering. Investigative Research: Partner with VCs, academic institutions, and industry bodies to commission teardowns that answer strategic questions—where is the secret sauce, and who holds the keys? Indian firms and engineers have all the technical talent, component access, and scale needed to join this league—whether for competitive intelligence, original R&D, or education. For every Indian engineer or entrepreneur who’s ever wondered “How does that work?”—grab a screwdriver and a microscope.
