Microsoft Graph file convert service is unavailable with 503 Service Unavailable

Question

We use Microsoft Graph File convert API to convert word(.docx) files to pdf

And convert API is failing with 503 Service Unavailable

our request details are as below

GET https://graph.microsoft.com/v1.0/drives/b!0dm-NWIVrUuB0R8YMNzPiMaYSpk38jNLnEVvRXPI9vn9u-elusw4SrWaCh8v8WjA/items/01RL4HXQGQYI3BD2AZDRGZXNENMYIGDCD3/content?format=pdf

And it gives following URL in location header (stripped of auth token)

https://northeurope1-mediap.svc.ms/transform/pdf?provider=spo&inputFormat=docx&cs=MTA2NGY3ZTQtYTllMi00NjdkLThkNDItZjQ1Y2M1OWYxNDVkfFNQTw&correlationId=bbbcbc79-430d-4a78-ac23-2b165291f4b9&docid=https%3A%2F%2Ffigg.sharepoint.com%2F_api%2Fv2.0%2Fdrives%2Fb%210dm-NWIVrUuB0R8YMNzPiMaYSpk38jNLnEVvRXPI9vn9u-elusw4SrWaCh8v8WjA%2Fitems%2F01RL4HXQGQYI3BD2AZDRGZXNENMYIGDCD3%3Fversion%3DPublished

Answer 1

Hi @Abdulkareem Nalband ,

Generally 503 service unavailable error may come when the service is temporarily unavailable for maintenance or is overloaded.

You may repeat the request after a delay, the length of which may be specified in a Retry-After header.

OR You can retry the requests or increasing the timeout(if you are using any custom application increase the timeout for at least 2 min).

errors

Sometimes it can happen with throttling. You should employ a back-off strategy similar to 429. Additionally, you should always make new retry requests over a new HTTP connection.
