authentication_error

[z-hunter]

Hi,
I'm trying to use Claude, and my API key is 100% valid, and there are credits in the account. I enter it from the command line:
: lua vim.env.AVANTE_ANTHROPIC_API_KEY="........"

Then I go to chat and type something, and in response I always get this message:

Error: {
message = "invalid x-api-key",
type = "authentication_error"
}

How can I check which key it's trying to log in with?
