Hi Team,

Need your help in resolving below error.

Error: '<' is an invalid start of a value. Path: $ | LineNumber: 0 | BytePositionInLine: 0.

Stack Trace: [Error] at System.Text.Json.ThrowHelper.ReThrowWithPath(ReadStack& state, JsonReaderException ex) at System.Text.Json.Serialization.JsonConverter 1.ReadCore(Utf8JsonReader& reader, JsonSerializerOptions options, ReadStack& state) at System.Text.Json.JsonSerializer.ReadCore[TValue](JsonConverter jsonConverter, Utf8JsonReader& reader, JsonSerializerOptions options, ReadStack& state) at System.Text.Json.JsonSerializer.ReadCore[TValue](JsonReaderState& readerState, Boolean isFinalBlock, ReadOnlySpan 1 buffer, JsonSerializerOptions options, ReadStack& state, JsonConverter converterBase) at System.Text.Json.JsonSerializer.ContinueDeserialize[TValue](ReadBufferState& bufferState, JsonReaderState& jsonReaderState, ReadStack& readStack, JsonConverter converter, JsonSerializerOptions options) at System.Text.Json.JsonSerializer.ReadAllAsync[TValue](Stream utf8Json, JsonTypeInfo jsonTypeInfo, CancellationToken cancellationToken) at System.Net.Http.Json.HttpContentJsonExtensions.ReadFromJsonAsyncCore[T](HttpContent content, Encoding sourceEncoding, JsonSerializerOptions options, CancellationToken cancellationToken) at OpenAI.Extensions.HttpClientExtensions.PostAndReadAsAsync[TResponse](HttpClient client, String uri, Object requestModel, CancellationToken cancellationToken) at OpenAI.Managers.OpenAIService.CreateEmbedding(EmbeddingCreateRequest createEmbeddingRequest, CancellationToken cancellationToken)

When I debug locally everything is fine.
But, when I access the code deployed as Azure Function, I am receiving above mentioned error.

Here is the code excerpt:
var result = await _gpt3.CreateEmbedding(new OpenAI.GPT3.ObjectModels.RequestModels.EmbeddingCreateRequest() { Input = text, Model = _config[SettingPropertyNames.gptEmbeddingModel] });

_gpt3 is an instance of OpenAI.GPT3.Managers.OpenAIService.

Regards

It is a simple prompt: when CI/CD pipeline will begin to run?

Most probably the response you are receiving is html instead of actual JSON format for the endpoint you are requesting. Please check that.
An as HTML usually starts with tag, the JSON validator fails on the very first character.
You should also clear any cache, that might be interfering with the returned data. (this has helped people resolve this same issue)

Thank you.
But the error is occurring in Betalgo package which I don't have control over.
Please refer to the stack trace.

Thank you all for your support.

Found the root cause: it is something to do with application's IP origin country.
