Error "Unexpected exception when initializing task 'Analyze Files': Failed to create an instance of translation provider TM .... "

Question

Hi all, 
 we are using the Studio API to create projects based on predefined project templates. The service sits on dedicated machine, i.e. this Studio service uses always the same user that has access to all project resources (Groupshare 2015 TMs und termbases). 
 There are no issues when using project templates with file-based resources or file-based TMs and Groupshare termbases. 
 When using templates with Groupshare TMs in some cases project creation works, in same cases, even when using the same templates and tranlatable files, the project creation fails (Unexpected exception when initializing task 'Analyze Files': Failed to create an instance of translation provider TM ...). Part of the Studio project files are created (folder structure, source and target files, sdlproj file), where it gets stuck is the analyses.. 
 I exclude this causes: access rights to Groupshare TM, available licences on the TM server, errors in the project templates, translation files that are not processed proprerly in Studio. 
 We have experienced this issue with the Studio 2015 and the Studio 2019 API. 
 A possible cause could be time-out problems, but I haven't seen any options where you can change/extend any time frames for Studio to complete project creation. 
 Has anyone experienced similar issues? 
 Regards, 
 Bruno Ciola

Hello Bruno Ciola , 
 
 Indeed it might be the case that some timeout issues occurs while retrieving information from the GroupShare. If the project files are not retrieved correctly, then the process of executing the project creation batch tasks will fail. You can use the Fiddler application to verify what's happening on the server side when retrieving the information from the GroupShare, and you can also try to add some timeout just to check if this might be the problem, see https://stackoverflow.com/questions/13513650/how-to-set-timeout-for-a-line-of-c-sharp-code topic. 
 
 With kind regards,

Hi Guys, 
 I have investigated a similar issue here this morning and might also solve the issue you have reported. 
 It seems that there is an issue in resolving the correct version of System.Net.Http assembly; the original exception is gobbled up with abstraction, which was preventing us from understanding the root cause in this case. You can work around this by simply making a hard reference to the same version of this assembly (that Studio 2019 is using) in your automation project. 
 Add this reference to your project: C:\Program Files (x86)\SDL\SDL Trados Studio\Studio15\System.Net.Http.dll
