Error getLDS()

[Kan-E]

Dear biomaRt team,

I ran the following code and encountered an error message.
Trying other mirror sites didn't resolve the issue.
Could you please advise on how to handle this error?

library(biomaRt)
genes <- c("LOC119647577","LOC119652571","LOC119654764","LOC119650780","LOC119654504","LOC119660709")
mart = useMart("metazoa_mart", dataset = "higca905115235v1_eg_gene", host="https://metazoa.ensembl.org")
ortho_mart = useMart("metazoa_mart", dataset = "dmelanogaster_eg_gene", host="https://metazoa.ensembl.org")
getLDS(attributes = c("ensembl_gene_id"),
       values = genes ,mart = mart,filters = "ensembl_gene_id",
       attributesL = c("ensembl_gene_id"),
       martL = ortho_mart)

error message:

Error: biomaRt has encountered an unexpected server error.
Consider trying one of the Ensembl mirrors (for more details look at ?useEnsembl)

Note: The conversion from human gene IDs to mouse gene IDs was worked properly under the same environment.

Thank you for your considaration.

I get a similar issue with mouse also:

> library(biomaRt)
> human = useMart("ensembl", dataset = "hsapiens_gene_ensembl", host = "https://jan2024.archive.ensembl.org/")
> mouse = useMart("ensembl", dataset = "mmusculus_gene_ensembl", host = "https://jan2024.archive.ensembl.org/")
> genesV2 = getLDS(attributes = c("hgnc_symbol"),
+                  mart = human, 
+                  attributesL = c("mgi_symbol"), 
+                  martL = mouse, 
+                  uniqueRows = TRUE,
+                  filters = "hgnc_symbol")

@Kan-E

The conversion from human gene IDs to mouse gene IDs was worked properly under the same environment.

Would you be able to share code that you got to work for conversion?

Hi! Getting the same issue here as well. At first I thought it was relating to issue #104 with Ensembl release 112, but setting a version and the host has not helped. The getBM() function also works fine.
