Getting Error 400 - Your client has issued a malformed or illegal request. That’s all we know

I am trying to connect Gmail with Appwrite. I have tried to make connection using explicit Client ID & Client Secret and also with predefined connection given in Appwrite. I have provided gmail.readonly access to appwrite for which I also received a notification email on my gmail account.
The base URL I am using is - https://gmail.googleapis.com/gmail/v1/users/me/messages

I have tried with/without headers, with/without query parameters but received same output every time.

"{\n  \"response\": {\n    \"status\": 400,\n    \"body\": \"<!DOCTYPE html>\\n<html lang=en>\\n  <meta charset=utf-8>\\n  <meta name=viewport content=\\\"initial-scale=1, minimum-scale=1, width=device-width\\\">\\n  <title>Error 400 (Bad Request)!!1</title>\\n  <style>\\n    *{margin:0;padding:0}html,code{font:15px/22px arial,sans-serif}html{background:#fff;color:#222;padding:15px}body{margin:7% auto 0;max-width:390px;min-height:180px;padding:30px 0 15px}* > body{background:url(//www.google.com/images/errors/robot.png) 100% 5px no-repeat;padding-right:205px}p{margin:11px 0 22px;overflow:hidden}ins{color:#777;text-decoration:none}a img{border:0}@media screen and (max-width:772px){body{background:none;margin-top:0;max-width:none;padding-right:0}}#logo{background:url(//www.google.com/images/branding/googlelogo/1x/googlelogo_color_150x54dp.png) no-repeat;margin-left:-5px}@media only screen and (min-resolution:192dpi){#logo{background:url(//www.google.com/images/branding/googlelogo/2x/googlelogo_color_150x54dp.png) no-repeat 0% 0%/100% 100%;-moz-border-image:url(//www.google.com/images/branding/googlelogo/2x/googlelogo_color_150x54dp.png) 0}}@media only screen and (-webkit-min-device-pixel-ratio:2){#logo{background:url(//www.google.com/images/branding/googlelogo/2x/googlelogo_color_150x54dp.png) no-repeat;-webkit-background-size:100% 100%}}#logo{display:inline-block;height:54px;width:150px}\\n  </style>\\n  <a href=//www.google.com/><span id=logo aria-label=Google></span></a>\\n  <p><b>400.</b> <ins>That’s an error.</ins>\\n  <p>Your client has issued a malformed or illegal request.  <ins>That’s all we know.</ins>\\n\"\n  },\n  \"request\": {\n    \"body\": {}\n  }\n}"

Please someone guide me where I am doing wrong. This is my first time using activepeices and I am trying to learn workflows. Thank you so much in advance!

Hello @Dron ,

Can you add the scopes shown in the image for the Gmail piece and test it again?
