Embedded dashboards break when selecting large numbers of filter values


We have multiple embedded dashboards live with our customers, however when selecting values from a filter the dashboards break when the number of selections is relatively large i.e. 80-100 values manually selected.

I've tested this across several embedded dashboards and for different filters/fields and the same issue seems to be occurring. In the normal metabase UI (non-embedded) everything works as expected.

We're on version 0.44.0

Many thanks,

Hi @dmellor
What is your definition of "break"? Are there errors? Check Admin > Troubleshooting > Logs.
Latest release is 0.44.4: https://github.com/metabase/metabase/releases/latest

Hi @flamber apologies for the vague terminology there - "breaks" as in all questions display "There was a problem displaying this chart."

In the logs, when I add an additional value to the filter (and the charts don't work still) the only thing I can see is :

[f23f082f-998e-4674-b8ca-85bdd051236c] 2022-10-12T12:04:19+01:00 WARN org.eclipse.jetty.http.HttpParser Header is too large 8193>8192

However (not sure if this is related), when loading the embedded dashboard with no filter selections, which does work fine, I do see this error (truncated):

@dmellor Allow larger headers: https://www.metabase.com/docs/latest/configuring-metabase/environment-variables#mb_jetty_request_header_size

You can ignore the missing field error:
