Serverless deploy fails - amazon-web-services

Question

Iam trying to deploy my lambda function to AWS using serverless. When executing
serverless deploy --verbose
Iam getting the following error every time:
Serverless Error ---------------------------------------
An error occurred: mainTable - Invalid KeySchema: The first > KeySchemaElement is not a HASH key type (Service: AmazonDynamoDBv2;Status Code: 400; Error Code: ValidationException; Request ID: EACEH0RDMBR36TR0DDBGODTRT3VV4KQNSO5AEMVJF66Q9ASUAAJG).

Can someone of you help?

When using KeySchemaElements, the HASH keytype must come before the RANGE keytype.
In your YAML, on you GSI for spinned-primary, you have to put the HASH keytype before the RANGE keytype; switch them around so that the HASH is the first keytype in that element.
