Cannot create glossary in Cloud Translation API v3 - php

Question

I'm playing around with Cloud Translation API v3 in PHP. I went through setup process and tried simple translation shown here and it worked. Then I wanted to test glossaries so I tried to add one as described here. When I'm trying to call the function:
protected function createGlossary()
{
$translationServiceClient = new TranslationServiceClient();
$projectId = 'my-project-id';
$glossaryId = 'my-new-glossary';
$inputUri = 'gs://bucket/file.csv';
$formattedParent = $translationServiceClient->locationName(
$projectId,
'us-central1'
);
$formattedName = $translationServiceClient->glossaryName(
$projectId,
'us-central1',
$glossaryId
);
$languageCodesElement = 'pl';
$languageCodesElement2 = 'en';
$languageCodes = [$languageCodesElement, $languageCodesElement2];
$languageCodesSet = new LanguageCodesSet();
$languageCodesSet->setLanguageCodes($languageCodes);
$gcsSource = (new GcsSource())
->setInputUri($inputUri);
$inputConfig = (new GlossaryInputConfig())
->setGcsSource($gcsSource);
$glossary = (new Glossary())
->setName($formattedName)
->setLanguageCodesSet($languageCodesSet)
->setInputConfig($inputConfig);
try {
$operationResponse = $translationServiceClient->createGlossary(
$formattedParent,
$glossary
);
$operationResponse->pollUntilComplete();
if ($operationResponse->operationSucceeded()) {
$response = $operationResponse->getResult();
printf('Created Glossary.' . PHP_EOL);
printf('Glossary name: %s' . PHP_EOL, $response->getName());
printf('Entry count: %s' . PHP_EOL, $response->getEntryCount());
printf(
'Input URI: %s' . PHP_EOL,
$response->getInputConfig()
->getGcsSource()
->getInputUri()
);
} else {
$error = $operationResponse->getError();
// handleError($error)
}
} finally {
$translationServiceClient->close();
}
}
it returns an error:
Failed to build request, as the provided path (google.longrunning.Operations/GetOperation) was not found in the configuration.
It throws error at $operationResponse->pollUntilComplete();. The file in bucket contains just one line - test,test.
Then when I try to call function that lists all glossaries, it works but it doesn't return any.
What can cause this problem and how do I add glossary?
