We have noticed getting 502 Bad Gateway Errors intermittently from Sheets API since Sept 15 and it has been getting more and more frequent ever since.
For reference, here are the Google Java Client libraries being imported:
<dependency>
<groupId>com.google.api-client</groupId>
<artifactId>google-api-client</artifactId>
<version>1.31.0</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>com.google.apis</groupId>
<artifactId>google-api-services-sheets</artifactId>
<version>v4-rev581-1.25.0</version>
</dependency>
The error originates at the point in code where we try to get the Spreadsheet using the id
Spreadsheet spreadsheet = service
.spreadsheets()
.get(spreadsheetId)
.execute()
The following is the error response
com.google.api.client.googleapis.json.GoogleJsonResponseException: 502 Bad Gateway
