Hi,

I am sorry that the issue was not solved completely...

Analyze task worked by adding project.save() but Pretranslation task fails even if save project is processed...
Could you please give some advice?

Trados Studio's build is 5889.5 (2017 CU 5)

[Expected result]
preTranslateTask.Status should be Completed.
The length of preTranslateTask.Messages is 0.

[Current Result]
preTranslateTask.Status returns Failed.
preTranslateTask.Messages includes ProjectAutomationException.

When adding the credentials please specify the url including the sdltm exactly as specified when creating the TranslationProviderReference.

new Uri($"sdltm.{ServerUri}{Organization}{(Organization != "" ? "/" : "")}{TmName}"))

Hi,

I'm having a same issue in that Analyze Files Task comes back with following error:

Unexpected exception when initializing task 'Analyze Files': Failed to create an instance of translation provider 'sdltm.http://nicgroupshare-test/?orgPath=/All Languages/Asian Languages/Japanese&tmName=Japanese RnD Test'.. AutomaticTaskExecuter

I have the project saved right before Analyze Files Task, but error still occurs.  This used to work for 2014, but it doesn't work with 2017...  

Could anyone help?

Thanks!
Rieko

Using Trados Studio, I opened the project that was created with API, and then run Batch->Analyze Files, it works fine.  Here's the Task History:  

Is this problem appearing on any project? Would you be able to share the entire error stack trace?

GS2017 CU4 makes the analysis reports available via the REST API so it might be a better and simpler alternative to just retrieve the analysis using the REST API rather than rely on Trados Studio Project Automation API.
