Hi Imesha, I was able to solve the issues mentioned in the last email. The issues in the wifi driver of my computer had caused those. Managed to get the React.js dashboard up and running as well, but still getting CORS issues therefore OODT ingested files are not shown in the dashboard.
I also hope to share my project proposal with you, as a Google doc, to get your feedback on it. Can you let me know if it is okay to share it with your personal Gmail address, or what process I should follow? Thank you Best regards Pavindu Lakshan On Sat, Mar 27, 2021 at 9:08 PM Pavindu Lakshan <pavindulaks...@gmail.com> wrote: > Hi Imesha, > > It took me several days to respond because of my university exams. > However, I went through the articles you mentioned and they helped me to > broaden my understanding of what Apache OODT is and its use cases.
