Errors when language server starts

[sbjqad]

I see these errors when the language server starts :

I have no idea where they com from. Any idea where to look ?

[gquerret]

This comes from the DF parser, probably when parsing the DF files specified in schemaFile attribute. The line number is specified after <unknown>. Can you paste the content of the line here?

[sbjqad]

This is such a failing line :

ADD FIELD "CreatedDateTime" OF "WhseAlgorithm" AS datetime-tz
DESCRIPTION "The date this record was created"
FORMAT "99/99/9999 HH:MM:SS.SSS+HH:MM"
INITIAL NOW
LABEL "Created Date"
POSITION 9
MAX-WIDTH 12
ORDER 80
MANDATORY

It does not understand the INITIAL NOW line.

[gquerret]

I assume that the DF file is not generated by the data dictionary, as the initial values would be surrounded by quotes. Though this is flagged as an error, that doesn't change the initialization of the LS.

[sbjqad]

No, we generate this ourselves indeed.

[gquerret]

I'll lower the severity of this message when starting the language server as there's no impact at this stage.

I also see this error when it starts :

[gquerret]

Can you check if this file is empty or invalid? The magic number is the first four bytes of the file. Expected values are 0x9d3ce56 or 0x56ced309 depending on the endianness.

[sbjqad]

The file is indeed invalid. This is my fault.

Thanks.
