Generated servicenames get too long

[Ksdmg]

When I try to generate a client for an endpoint on our ERP system, I get the following exception:

04/12/2023 14:30:54:       error generating the client: The filename, directory name, or volume label syntax is incorrect. : 'C:\Users\schaafa\AppData\Local\Temp\cefe13ac-3a41-4719-be69-731318288748\Item\ErpBOLaborSvc\TimeWeeklyViewsWithCompanyWithEmployeeNumWithWeekBeginDateWithWeekEndDateWithQuickEntryCodeWithProjectIDWithPhaseIDWithTimeTypCdWithJobNumWithAssemblySeqWithOprSeqWithRoleCdWithIndirectCodeWithExpenseCodeWithResourceGrpIDWithResourceIDWithLaborTypePseudoWithShiftWithNewRowTypeWithTimeStatus'

This is the command I was using:

kiota  generate -l CSharp -d C:\MyService.json -o C:\Users\schaafa\AppData\Local\Temp\cefe13ac-3a41-4719-be69-731318288748 -n Incoe.Epicor.Kiota.OpenAPIs

Here is the service file:
MyService.json

Hi @Ksdmg
Thanks for using kiota and for reaching out.

This is caused by this endpoint in the description:

/{currentCompany}/Erp.BO.LaborSvc/TimeWeeklyViews('{Company}','{EmployeeNum}',{WeekBeginDate},{WeekEndDate},'{QuickEntryCode}','{ProjectID}','{PhaseID}','{TimeTypCd}','{JobNum}',{AssemblySeq},{OprSeq},'{RoleCd}','{IndirectCode}','{ExpenseCode}','{ResourceGrpID}','{ResourceID}','{LaborTypePseudo}',{Shift},'{NewRowType}','{TimeStatus}')

Questions:

• Since you're using OData, are you using OpenApi.Net.OData to convert your EDMX model into an OpenAPI description? If so, can you provide the convertionSettings you set?
• Do you need this endpoint in your client? If not, have you tried excluding it using include/exclude path parameters?

[Ksdmg]

Thanks for your fast response!
I'm not in control of how this schema is generated. It's from our ERP system Epicor, so I cannot share any details about how this schema is generated.
I could exclude this endpoint for now, but I might need it in the future.

[baywet]

Great, exclude it for now then, and if you need it later, please point the vendor to this thread.
Basically my suggestion was to change one of the conversion setting so the path parameters become query parameters instead. like we do for Microsoft Graph

[Ksdmg]

I mean this is a fix for now, but I don't think that Kiota should only work if existing schemas get changed by big companies, which honestly will never happen.
As far as I can tell the only issue is the path length of the generated files. Can you add a setting that allows me to cut off long method names? Like allow max 20 characters?
I'm now busy removing all methods that create too long filenames, which feels kinda stupid because kiota COULD generate it, it's just a issue with the filename.

[baywet]

Thanks for the additional context, we could do like we do for go: use a hash for the file name if the name becomes too long.
@andrueastman is this something you think you could take over?

Sorry I missed this one @baywet. Acknowledging this one and will take it over.
