Hi @Navaneeth_Kumar ,
Welcome to the forum! Could you post a code snippet (obscure your bearer token and any other personal info)?
Are you asking to return a very large data set? I just tried this myself for a team with ~500 projects and I got an error when I opted in for a ton of fields, but when I slimmed down to just a few fields, it ran ok. I saw in this forum post that there is a hidden (undocumented) data limit (even with the auto-pagination the library runs), so it could be that.
