> It seems to me that =evn is incorrect. According to the source code, the
> correct value should be the class name. for example:
> `org.apache.kafka.common.config.provider.EnvVarConfigProvider`
> ```
> for (String provider : configProviders.split(",")) {
> String providerClass = providerClassProperty(provider);
> if (indirectConfigs.containsKey(providerClass)) {
> String providerClassName = indirectConfigs.get(providerClass);
> if (classNameFilter.test(providerClassName)) {
> providerMap.put(provider, providerClassName);
> } else {
> throw new ConfigException(providerClassName + " is not
> allowed. Update System property '"
> + AUTOMATIC_CONFIG_PROVIDERS_PROPERTY + "' to
> allow " + providerClassName);
> }
> }
> }
> ```
