When trying to send email using Gmail connector FileNotFoundException is occurred - wso2

Question

I'm using WSO2-Integration-Studio-7.0.2-linux-gtk-x86_64.
I tried the steps in https://ei.docs.wso2.com/en/latest/micro-integrator/use-cases/tutorials/using-the-gmail-connector/
When I execute the POST request in the tutorial from Micro Integrator, I got below execption.

When I checked the directory of "/data/wso2-products/WSO2-Integration-Studio-7.0.2-linux-gtk-x86_64/IntegrationStudio/runtime/microesb/registry/governance/connectors/Gmail/", there is no .metadata folder. Is there any step missed in the document?

Answer 1

It worked with Micro Integrator 1.2.0.
Best way is Download Integration Studio 7.1.0 which has inbuilt 1.2.0.
Open your existing workspace with new Studio. Dont forget to copy your existing configurations from deployment.toml file.
