I have an Azure Function with an environment variable set to obtain the value from a key vault:
@Microsoft.KeyVault(VaultName=<vaultName>;SecretName=<secretName>)
We are getting issues when the value in the key vault has an “=” in the secret, e.g.
thisisaverygoodsecret=
If we store the secret against the environment variable directly, the application works as expected. I assume we need to escape the = in some way, but I can’t see anything in the Microsoft docs.
We have several other Function variables obtained in the same way, so there is no problem with the link to the Key Vault.

I have added @Microsoft.KeyVault(VaultName=<vaultName>;SecretName=<secretName>) in App Settings which has = in its value.
I have used Environment.GetEnvironmentVariable("secretValue"); to fetch the secret value from key vault and got the expected response.

name = name ?? data?.name;
