Question

When trying to run the command yarn install, the following error message is displayed:

"Internal Error: Expected an indexed object, got a string instead. Does your file follow Yaml's rules?"

My .yarnrc.yml is syntactically correct. What is the cause of the error?

• Yarn v3.2.2
• Node v16.14.0

Deleting the yarn.lock file from the same folder and running yarn install afterward solved the issue.
